SCIsome kind of popular science
Hello again science lovers!
I have good news and bad news for you. Bad news is, this is the
last edition. Because my EVS project ends and I will not share my
articles with you any more. First good news: with this you got
totally 3 SCI magazines which were written during my EVS project,
3 good memories on your shelf. Second good news: In this edition
there are also articles of my friends, with whom I work in MCDD.
Besides their own personal projects, they contributed to my
magazine and it is a big pleasure for me to share their articles with
you.
Olga Vincente Lorenzo introduces you Maria Montessori, a very
succesful female scientist from 19th century. Leonardo Garcia Diaz
offers an alternative solution to combustion engine cars by
informing you about electric cars. Emre Uysal tickles your brain
with paradoxes and surprizes you with impossible objects. Janberk
Turan tells you how most of ideas in science fiction books and
movies became true altough they were just dreams and fantasies in
the past .
You will also find interesting articles about 3D printers, Mars-
one Project, new technologies, popcorn, and more. Enjoy!
Special thanks to my host organization, Mladinski center
Dravinske doline, for all their support about my personal project.

MARIA MONTESSORIMaria Montessori was educator, scientist, doctor, psychiatrist,
philosopher, psychologist, feminist and humanist Italian. She was
born on 31 August 1870 in Chiaravalle in the province of Ancona,
Italy, in a bourgeois Catholic family.
She was beyond time which she lived in. She studied
engineering when she was just fourteen years old, after biology
and finally medicine. In that time the highest aspiration for women
was to be a teacher, but she studied medicine at the University of
Rome. She became first female doctor in Italy. At those times at
University of Rome women were not allowed to study medicine.
Still nobody knows how she got her
graduation. But she was a doctor with
the best qualifications. Shortly after
she started to work as an assistant in
the department of psychiatry of
University of Rome. At this time she
was interested in the education of
children who had some kind of mental
deficiency, and applying experimental
methods. She managed to teach those
children how to read and write.
Disabled children could overcome
exams which are for normal children. She thought that if this
method worked for disabled children, with "normal" children
results would have been amazing.
In 1907 in Italy the first House of Children (House for children
with social-economic problems) was inaugurated in San Lorenzo,
Rome.
‘Within the child lies the fate of the future’
Montessori with children

The Minister of Education pretended that it served to control
children, but the House of Children became an important
investigation center in very short time. Maria Montessori, as a
director, got four or five years old children who has troubles,
taught them how to write and read in natural way. At the same time
she began to develop her own method by
using the observing systematic and by
elaborating new pedagogy.
She was the creator of the Scientific
Pedagogy and a new revolutionary way of
education. Her educational principles
were based on atmosphere-children-love
triangle.
The minds of children have wonderful
and unique ability: the ability to acquire
knowledge by absorbing with their
psychic life. They learn unconsciously,
gradually passing from the unconsciousness to consciousness,
moving along a path where all is joy. They were compared to a
sponge, with the difference that the sponge has a limited
absorption capacity; the child's mind is infinite. Knowledge comes
into their head by the simple fact of living.
Obviously the first period of human development is the most
important. It is the stage of life there is more need of aid. They need
aid, not because they are deemed insignificant and weak, because
they are endowed with great creative energy and fragile nature. So
these valuable features must be protected.
The prepared atmosphere allows the child to develop without the
constant help and supervision of an adult. The design of this
atmosphere is based on the principles of simplicity, beauty and
order. There are bright and warm spaces, including language,
plants, art, music and books. The living room is organized in work
areas equipped with tables adapted to the size of children and open
areas for work on the ground.

Scientist of the monthMaria Montessori
In each development area the materials are organized
systematically and in sequence of difficulty. The role of teachers is
to teach each child individually. The highlight is, it imposes no
lessons to anyone; their work is based on guiding and helping each
child according to his/her needs, and can not intervene until they
need it, to direct their mental activity.
The level and type of intelligence is formed primarily during the
first years of life. In 5 years, the brain reaches 80% of its adult size.
The children's plasticity of education shows that the potential
should be exploited starting early. Knowledge should not be
introduced into the heads of children. On the contrary, using their
own knowledge must be perceived by them as a result of their
reasoning. The most important thing is to motivate children to
satisfy their curiosity and experience the pleasure of discovering
ideas rather than receiving knowledge from others. Allow the child
to find the solution of the problems. Unless it is very necessary,
don’t bring new knowledge from outside. Allow them to build their
knowledge based on their specific experiences. With respect to
competences, this behavior should be introduced only after the
child has confidence in the use of basic knowledge. As Montessori
says: ‘Never leave the child to fail if there isn’t any reasonable
chance to succeed’.
She believed that they could not create geniuses. But to give
opportunity to fulfill their potential would make them
independent, secure and balanced human. Another innovative
concept was that each child marks their own pace or speed to learn
and that time must be respected. Maria Montessori developed a
specific educational material that is fundamental for the
development and implementation of her method. It is not just a
hobby, not a single source of information, it is more than that, it is
educational material for teaching. It is designed to capture the
curiosity of children. It is a guide for education through the desire
of learning. To achieve this goal has to be presented grouped
according to their function, according to the innate needs of each
student.
5
Educational materials can be used individually or in groups by
participating in storytelling, talks, discussions, cooperative work,
singing, outdoor games and free play activities. This ensures
communication, exchange of ideas, learning the culture, ethics and
morality. In general all teaching materials have a degree more or
less elaborated of the four values: functionality, experimentation,
structure and relationship. Another feature is, almost all
equipment is self-correcting, so that no task can be completed
without the children realizing
their mistakes by themselves. If a
task performed incorrectly they
find gaps or leftover pieces. The
children do things by themselves,
use simple devices and see
growing things (plants, animals),
open their mind to science. The
colors, papers of different
textures, multiform objects and three dimentional geometric
figures encourage creative expression.
Since 1926 the Montessori Schools were extended around the
world. She continued studying, writing and giving a lot of
conferences. For her important works in the education field.
University of Amsterdam awarded her with Honoris Causa. She was
also proposed for Nobel Peace Prize three times.
It is difficult for us to understand the impact of Maria
Montessori in the reform of teaching methods in the early
twentieth century. Most of her ideas seem now obvious or even too
simple. But at those days they were radical innovations, which
produced great controversy and important changes.

A sciene from movie about Montessori
MARS ONE PROJECT Just a century ago, travelling to outer space was just a fantasy
which we could just dream about. Big space adventure started in
1961 when Yuri Gagarin first time went to outer space and reached
an incredible point with a fantastic project aims to establish
settlement on the red planet Mars.
A few entrepreneur scientists in Netherlands established a non
profit organisation called Mars One. The big goal is creating a
permanent human colony on the planet Mars in 2023. Idea of
project has been started in 2011. Founding members of Mars One
came together to develop the strategic plan. In 2012 project was
declared to community with all details of its mission. For this hard
mission brave and eager people were wanted. They made an open
call to all around the world with just one
condition: people had to be over
18. Just in second week 78,000
candidates were allready
applied for project. Now this
number reached over 100,000.
Selection of volunteers will be
completed in 2015 and they will
start their 8 years long training to
be educated as astronauts. After a
tough and long term training, in
2022, they will be ready to start
their journey from Earth to Mars.
Journey will take 7 months and
when they will reach on the surface
of Mars great adventure will start.

Mars One ProjectGreat space adventure
After arrival, new inhabitants of red planet will need to face a big
challenge. At least first 6 months they will have to accomplish a lot
of construction work. They will build structures for themselves to
live in and to make research. Step by step they will start to create a
new stable life on the planet.
Candidates who are chosen to achieve this mission have to make
the hardest decision in their lifes. They won't see their family again,
won't pet their cats at least once again, won't taste a warm pizza
ever again... Because it is a one way trip and there is no turn back!
For the first time 4 people will be sent, consist of 2 women and 2
men. Each year 4 more people will be added. For sure there must be
a huge preparation process and there are a lot of obstacles and
limitations to be achieved. Howewer, each step was allready
planned. In 2016 SpaceX-Dragon module will be prepared it must
have 2,5 tons of food capacity. In 2018, an explorer vehicle will start
to work on Mars to detect the place for settlement. 1 discovery
vehicle, 2 life units, 2 life support units and 2 support units will be
launched by Dragon Module in 2021. After all preparations,
conditions will be approppriate to support human life on the planet.
As we know from previous experiences, less than half of modules
could reach Mars surface which were sent. This information lets us
think how risky sending human-carrying modules is. While there
can be a big danger during travel from Earth to Mars, it is also
possible that they can have various safety problems after arrival. oFirst of all, surface temperature is -55 C and there are powerful
radiation which they always have to be protected. In addition, lack
of food or water can be a big problem.

Mars One Project
They can also have some serious
psychological problems because
they will be all the time under
pressure because of hard life
conditions.
From the beginning of their life
on Mars, daily life of astronauts
will be recorded all the time and their adventure will be a reality
show on TV. Income from this reality show will be reused for
finances of Mars One project.
Actually, if we think about feasibility of the project, it looks
impossible. They need a lot of money, too much hard work and high
technology equipment to achieve everyhthing. Most of people don’t
believe that project owners can manage it or not. Anyway, most of
us will live until 2023 and we will see that they accomplish or not.
More or less you know the details now. So you still have time to
be a candidate for the project. Good luck!

This morning you may drink your coffee from special cup which
you designed last day. You may give a tiny copy of your friend for
her birthday. It is possible to print a new piece for your car. Girls
can use their own designed jewelery or shoes whenewer they
want... These are not dreams, they happened and are happening.
Also we don't need to wait to have them in our daily lifes. In my
opinion, they are one of the best devices invented in last 50 year.
Story of 3D printers started with idea of Charles Hull. In 1984 he
produced first 3D object by using digital data. In 90's a lot of
companies invested in 3D printing technology and some
interpreneurs established new companies to produce their new
developed 3D printers. Today this technology is very common. I
think you don't have to wait too much to have one for your home.
What are 3D printers? They are devices which produce 3D objects that are converted
from computer designed drawings to real solid objects without
need for extra mold or fixture by using different kind of materials.
3D printing is an additive technology in which objects are built up
in many thin layers. They work at the same principle
as prototyping devices. It is also possible to find
some prototyping devices which are faster and
have better quality. They are usually used
for producing pieces in automotive and
aerospace industy. On the contrary, 3D
printers are smaller, cheaper and they are
more appropriate for home use. That's why
they are chosen for daily use.
3D PRINTERS
A home type 3D printer10

3D printersToday & future
How is possible to print? First of all, you need a drawn 3D model of your object in your
computer. Some softwares which can be used for this purpose are
AutoCAD, SolidWorks, Google Sketchup, Rhino3D Autodesk
123D... Models which are designed by these programs sould be
converted to STL document and exported to printed to be produced.
A wide range of materials can be used to produce your model such
as polimers, ceramics, stainless steel, brass, bronze, poliamide,
resin, titanium, silver, gold, even chocholade or cheese!
Different kind of technologies can be used for 3D printing.
Difference between technologies is related to method how they
generate layers of object. Some common technologies which are
used for 3D printing are selective laser sintering, fused deposition
modelling and stereolithography.
For which purposes 3D printers can be used? Today, 3D printers are used for wide range of purposes. Besides producing objects for hobby or for your daily life, they are also used for producing prototypes before industrial manifacturing. Also in medical science implants are printed by 3D printers. It is possible to print very complicated objects or moving pieces as you can see in the picture. Some companies offer you to print your personal designed object and send it to your home. If you have a computer program that you can design your own 3D object with and if you are good at designing, you can design your favorite object by yourself and order it as a real object on internet. For example you may be interested in this web page http://i.materialise.com which belongs to Materialize Company.
2511
When you prepare your design and choose material it shows you how it will look like and how much will it cost. If you want to purchase it, they send it to you by post. There are 17 different material choices and there are information about materials. Besides this, you can see and buy other objecs which designed before. In the near future, women will design their own shoes and print them out at home or they will be able to send their designs to print shops and let them be produced there. There are no limits about 3D printing. Blizzdent Company produced a tooth cleaner by 3D printing. According to your mouth shape you get your personal cleaner. They claim that it makes perfect cleaning just in 6 seconds. An engineering company Solid Concepts could produce a gun by 3D printing but they had trouble with Disarmament and international law in USA. Of course, non of us wants 3D printers to be used for weapon production. Nowadays, medical and biotechnological applications of 3D printers are rising. A lot of applications are allready started from producing arm implants to periodontic applications. In addition scientists started to work on producing artificial organs, tissues, muscle fibrilles and vascular systems. They call this method 'bioprinting'. There are different kinds of 3D printers which you can find on internet. Their prices changes according to their properties. Maybe it is time to buy one and start to print your ideas!

Google Glasses Meet the newest technology of Google Company. With this new
technologic device you will carry your mini computer all the time
right in front of your eyes. When you are dancing, celebrating your
child's birthday, visiting a museum, this glasses will be always with
you. You just need to say 'OK glass, record!' or 'glass, take photo!'
When you travel to a new city and you
want to have more information about
architecture, you can google it
instantly. During your travel in another
country, it will be your best helper to
translate all signs and information
around you. All of these, you will do
hands-free! Poperties of google glass
are: The display is the equivalent of a
25-inch high definition screen. From around 2.5 meters away 5
megapixels camera that can capture video at 720p resolution. The
rechargeable battery last for roughly a day. There's 16GB of flash
memory built into the device, although only 12GB is currently
available for user storage. Bluetooth and WiFi will be built in, but
there is no GPS chip, so the Glass will probably work best alongside
an Android phone for full Google Maps functionality. You can
however pair it with any Bluetooth enabled phone and would
expect some support for IOS at least. Sound will be produced
through bone conduction transfer - vibrating your skull to
transmit to your eardrum. Google recently revealed a new version
of the Glass headset that can take an optional mono earbud if you
need to wear Glass in a noisy environment where bone conduction
just can't give the volume you require.

Wireless Chargers Electricity converted to electromagnetic field with an induction
coil by wireless charger. This electromagnetic field is transferred
to cell phone's battery. A secondary coil in mobile phone receives
electromagnetic field and again converts it to electric current to
use in mobile phone. Actually this
technology has been used from 90's.
For example Oral-B rechargeable
toothbrushes by the Braun company
have used inductive charging since
the early 1990s .
We will discuss about the most
famous companies which produce
wireless charging technology: Nokia,
Samsung and Google.
Nokia Lumia 920 has wireless
charging built-in. And you can charge Nokia Lumia 820 wirelessly
by adding on a wireless charging shell .
Nexus wireless charger by Google company is compatible
for any device which has inductive charging property. Nexus
Wireless Charger is officially supported by the Nexus 5, Nexus 7
and Nexus 4, since each has wireless charging built-in. It has a
glass-like top that is a fingerprint magnet, soft-touch sides, and a
super sticky bottom that helps it adhere to your desk.
Samsung Company has produced very elegant wireless charger
and developed Galaxy S4. You can use this smart phone with its
normal back cover or special cover which has wireless apparatus.
The charger is also compatible for other smartphones.

Keyboard revolution Everybody knows that it is hard to type
on the screen of mobile phones. To write
your messages or mails more comfortable,
iPhone has an application which you can
download from iTunes for free. You just
need to print out its special keyboard and
put your iPhone to the right place. You can
do everything like it is a real keyboard,
such as chatting with your friends, playing
games, typing texts. It is also practical because you just carry a
piece of paper in your pocket and use it anywhere you want. The
phone's camera detects your fingers with state of art algorithms.
The fastest DNA sequencer DNA sequencing has revolutionized medicine and biomedical
research. For example, DNA analysis can tell doctors which drug
might work best against a particular cancer. But current
technology usually sequences only short stretches of DNA and can
take hours or days. But with this new sequencer, it is much faster
than you can imagine. There are 5 steps which you can follow and
than your DNA strands will be sequenced. First of all you drop pure
DNA or blood on the chip. DNA is divided into two single strands by
an enzyme. Due to amount of nucleotides, electrical currency
interrupted in nanopores and a sensor records this electrical
disturbance. In next step electric signals are recorded by a
software. After all you need to do is to check errors of your
information. 70,000 base pairs can be sequenced with this device.

Present or future? Unfortunately for environment the answer is future. Why? From
my point of view there are two main answers.
First one is: this technology is more or less new and still is not
very good developed. There is problem about batteries: how many
kilometers you can run with one full battery? At the moment the
longest distance is between one
hundred fifty and two hundred
kilometers (With electric car,
hybrid is different). That’s why
people who think to buy electric
car aren’t still convinced. Also
there is other one more problem:
There aren’t any ‘charge points’
in all cities, so if you want to buy
an electric car, first you must
check if there is one of this
points close to you or not.
Second problem is about economic interest. As you know big
petrol companies are so rich and they can control even car
companies with the aim of avoiding them to sell good and really
usefull ellectric cars. I think, big petrol companies pay to owners of
cars companies to be silent about new
electric car technologies. Now I would like
to tell you what are the different kinds of
electric cars that already are developed.
Electric powered vehicles (E.V.) are
powered by electricity and they need to be
connected to an external power source for
charging.
An electric car on charging
16
Electric carsPresent or future?
Actually inside of this group there are three kinds:
Electric Battery Vehicles (E.B.V.): The battery electric vehicles or
E.B.V. have a battery as a power supply. They can be plugged into a
charger or in some cases, depleted battery can be replaced with
charged one. The E.B.V. hasn’t got a fuel tank, exhaust pipe like
conventional engine or any integrated electricity generation
source.They usually can travel from 100 to 160 km.
H.E.V. plug-in: Plug-in hybrid
electric vehicles have two power
systems. In some H.E.V. plug-in
cars, the main power source is a
battery, a secondary engine
generates additional electricity
from gasoline when the battery
runs out. These cars usually can
travel from 40 to 80 km by battery
power, which extends hundreds of
km with fuel generated electricity. Other H.E.V. plug-in cars use a
conventional gasoline engine as the main power source and
supplemented with a battery that can be recharged by plugging.
This type of hybrid vehicles usually have an electrical path from 16
to 24 km, which extends hundreds of kilometers when the gasoline
engine is being used.
Hybrid Electric Vehicle (H.E.V.): Hybrid or H.E.V. electric
vehicles have two or more power systems, usually a battery and a
conventional engine. In H.E.V. regenerative braking generates
electricity to charge the battery, which provides a secondary power
source to the conventional engine. These vehicles can only travel
short distances (5-6 km) with battery and can’t be plugged in a
power grid.
Now in the automotive market you can find many car companies
that sell electric cars. For example Toyota was the first company
which developed an hybrid car that really works well: Toyota Prius
Hybrid.
If you can find some charging points in your city, you’re lucky!
17
Present or future?Electric cars
After that the automotive giants started to sell their own electric
and hybrid cars: Renault Kangoo Electric, BMW i3, Peugeot iOn,
Nisan Leaf...
Now let’s talk about advantages of electrics cars. The use of an
electric vehicle represents a significant saving to the consumer's
pocket. Its main economic advantage comes from the type of energy
use: electricity. It is much cheaper to recharge an electric car than
fill the tank of internal combustion car with gasoline. So that, the
initial expense of buying an electric car is amortized over several
years through savings in fuel. Especially when you consider about
gasoline prices, they increase in short and medium term. Aside
from fuel, electric cars have significant maintenance savings,
because they don’t use oil or other lubricants. They have a little
brake wear and they don’t have mechanical transmissions.
Furthermore, energy efficiency of the electric vehicle is almost
double times more than internal combustion car. According to the
European Commission, an electric car has an efficiency of 60%,
when conventional engine cars have 20%.
Finally, we must not forget the important advantages of electric
cars for the environment which also has economic benefits,
particularly for the society. The most important thing: the exhaust
of these vehicles don’t emit carbon dioxide. So they help to reduce
greenhouse gases and air pollution caused by emissions from
conventional cars. Moreover, their engines are virtually silent and
have no vibration, which helps reducing noise pollution.

Here is not written ‘Paradox’
What is paradox? As you can see in title, it confuses you. There is
written, 'there is not written paradox' but in fact, there is written
paradox! That is a paradox. Paradoxes are interesting, surprising
and they tickle your brain.
Description of paradox from wikipedia: ‘A paradox is a
statement that apparently contradicts itself and yet might be true.
Most logical paradoxes are known to be invalid arguments but are
still valuable in promoting critical
thinking.’
Liar paradox (Epimenides) Cretan phylosopher Epimenides created
first paradoxes. His most famous paradox
is 'liar paradox'. He made confuse people
around him when he said ' All Cretans are
liars'. Thomas Fowler (1869) states the
paradox as follows: Epimenides the
Cretan says 'all the Cretans are liars' but
Epimenides is himself a Cretan; therefore
he is himself a liar. But if he is a liar, what
he says is untrue, and consequently the Cretans are veracious; but
Epimenides is a Cretan, and therefore what he says is true; saying
the Cretans are liars, Epimenides is himself a liar, and what he says
is untrue. Thus we may go on alternately proving that Epimenides
and the Cretans are truthful and untruthful.'
PARADOXES AND IMPOSSIBLE OBJECTS
19
Liar Pinocchio paradox
The twin paradox
One of the most famous
paradox is Einstein's
twin paradox. One of the
twins is staying on
Earth while his twin was
moving in space. After
39 years twin on the
Earth became 72 years
old and then his twin
returned suddenly. He couldn't recognize him. The other twin was
moving in space at almost speed of light. When he came back to
earth after 39 years, he remained almost the same while his twin
became old. So, he couldn't recognize him.
Impossible Objects An impossible object (also known as an
impossible figure or an undecidable figure)
is a type of optical illusion consisting of a
two-dimensional figure which is instantly
and subconsciously interpreted by the visual
system as representing a projection of a
three-dimensional object although it is not
geometrically possible for such an object to
exist (at least not in the form interpreted by the visual system).
In most cases the impossibility becomes apparent after viewing
the figure for a few seconds. However, the initial impression of a
three-dimentional object remains even after it has been
contradicted. There are also more subtle examples of impossible
objects where the impossibility does not become apparent
spontaneously and it is necessary to consciously examine the
geometry of the implied object to determine that it is impossible.

Brain tickling
Penrose stairs
Swedish artist Oscar Reutersvärd was
the first to deliberately design many
impossible objects. He has been called ‘the
father of impossible figures’. In 1934 he
drew the Penrose triangle, some years
before the Penroses. In Reutersvärd's
version the sides of the triangle are broken
up into cubes. In 1956, British psychiatrist
Lionel Penrose and his son, mathematician
Roger Penrose, submitted a short article to
the British Journal of Psychology titled
"Impossible Objects: ‘A Special Type of
Visual Illusion’. This was illustrated with
the Penrose triangle and Penrose stairs.
The article referred to Escher, whose work
had sparked their interest in the subject,
but not Reutersvärd, of whom they were
unaware. The article was published in
1958.

SCIENCE PAGES Everybody knows what is science fiction, but most of people think that
science fiction is just space, spaceships, aliens, monsters. But it is not
true. Mainly science fiction movies or books try to answer where
humanity is going. This is really good question, because it never ends.
During existence of mankind in the world, this question will be with us
and we will wonder about the answer.
To be a science fiction writer is one of the most amazing jobs in the
world. You need to have wide scientific knowlegde and also you need to
have a crazy mind. If you don't have it, please don't try to write something
about science fiction. In my opinion, science fiction writers live in the
future in their minds. Maybe physicaly they are here with us but mentally
they are many years ahead.
Most of invention ideas comes from science fiction books or movies.
When Jules Verne wrote ‘Twenty Thousand Leagues Under The Sea’, there
wasn't this much submarine technology. After, our
technology has progressed and we have similar
technologies as written in his book. Also when Mary
Shelly wrote ‘Frankenstein’ people didn't know
anything about the transplantations. These are just
some examples. So many ideas which we use now in
daily life, comes from science fiction books.
If we talk about science fiction history, it stared at 2nd
century with Lucian's ‘True History’ and some stories of
‘Tales of 1001 Nights’. They are kind of science fiction. But in
my opinion, gods of science fiction are Jules Verne, H. G. Wells
and Hugo Gernsback. Also most of people have the same idea.
When Jule Verne was a little child, he lived in a town near the see and
he always interested in sea, ships and travelling.
SCIENCE FICTION: PRE-FUTURE

Pre-futureScience fiction
When he was 12 years old, he ran away from home
and joined a ship crew. But his father caught him
and brought him back. It is said that after that
moment Jules promised his father that he will just
travel in his mind. Maybe it is true maybe not. But
the truth is, he had great imagination. 'From
Earth to the Moon', 'Twenty Thousand Leagues
Under The Sea', 'Journey to the Center of The
Earth' and more of them are books that were
beyond the current time when they were written.
H.G. Wells was also one of the pioneers of the science fiction. His books
are different than Jules Verne's books. Because he mostly didn't write
about technology. He mostly wrote about the impact of technology on
society. Hugo Gernsback was the owner of the first science fiction
magazine in history, 'Amazing Stories'.
If I talk about movies, I can say that Star Wars and
Star Trek series are two of the best science fiction
examples. Some people don't think like that but in my
opinion both of them have stories beyond the time.
Robots, lightsabers, spaceships, teleportation
devices and most of the ideas are great. In my
opinion, especially Star Wars is important for laser
technology. Lightsabers are kind of lasers and in
those time we didn't use it for some purposes yet. Also
we watched a lot of movies about robots and
computers and most of them came true.
As everybody knows, most popular theory in science fiction movies is
taking control of the world by computers. Maybe Matrix is more
imaginary story but computer technology is getting better and better.
Every year scientists invent more sensitive robots and much more people
become to be addicted to this technology. Maybe in the future, maybe in a
shorter time than we guess, technology can take the control. Who knows?

He explains working principles of a lot of devices with engineering
details and gives technical
information under this slogan: 'The
engineering details of all the stuff
you wanna know about'. He offers
videos and articles about many
topics such as structure of
fiberoptic cables, how transistors
work, what is the working
principle of open ring of soda
cans... As you can find all of these
in webpage, you can also search for
them in Youtube by using keywords. If you are impressed by ideas
and explanations of this 'Engineer Guy', you may have his book '8
Amazing Engineering Stories'. This book is available as hardcopy
and e-book.

bacteria became an artwork as they are growing
in petry dish and you will appreciate how
beautiful results can happen when science and
art come together. Artist-scientist Klari Reis,
creator of this blog calls this kind of art 'Petri

Actually I have seen different kind of
petri arts on internet before, but this
one is very proffessional and impressed
me a lot. Klari everyday adds a new
petri painting. This artworks can be
followed day by day. She creates names
for each work according to her
inspiration arising from their beauty,
such as Lemonade slushy, Lychee
coctail, Jelly belly bowl... If you are
interested about other artworks of her,
you can also visit www.klariart.com.
There is online shop link which can be
clicked for ordering her artworks. She is also reachable on
Facebook and Twitter.
www.sciencebob.com Perfect source for children and
families! Children can find opoortunity
to understand some scientific facts
better by watching videos. How lava
lamp can be made? How can your hair be
funny with static electricity? How does
Van de Graaff generator work? There
are videos to answer such kind of
interesting questions. Experiments can
be done easily at home or at school with friends. This is a good way
to discover fun part of science.
Materials for experiments and methods
are explained very detailed. Also you
can order some science kits or book
from bobstore link.

www.scaleofuniverse.com Just push the start button and explore all universe from
microcosmos to macrocosmos. Creators of the webpage prepared
beautiful images which are helpful when comparing sizes. When
you start your travel through dimentions, you can adjust sizes by
sliding the bar below the image to left or right.
During your travel
you will have fun and
learn size of different
objects in the universe
from width of DNA to
diameter of a star
which is ten times
bigger than our sun.
The window which
appears when you click
on an object, offers
you more detailed
information.
In observable universe link there are photos which shows you
location of Earth in the Solar System, Solar System in Milky Way,
Milky May in local galactic groups, local galactic groups in local
superclusters... On each map you will realize how small is the
previous map. When you look at observable universe map, the last
one, it can make you feel so small and insignificant in whole
universe. But don't take it so seriously and enjoy your short life!

DID YOU KNOW? How popcorn pops? Popcorn is one of the most common snacks in the world. It is
usually with us when we have a party with our friends, when we
watch a movie in cinema. But do we know what is going on when
you put corn kernels in the pan or microwave?
First of all you need to know that there are 4 different corn
species and just one of them has popping property. Because, corn
kernels must have some main physical characteristics. Popcorn
differs from other types of corn in that its hull has just the right
thickness to allow it to burst open. A popcorn kernel consists of 3
main components: germ, endosperm and pericarp. Endosperm has
starch inside and there must be between 13-14% of water in the
starch to be able to make the kernel explode. Pericarp must be hard
and resistant enough to withstand the pressure inside during
cooking process. Because the counter force must be kept until
moisture reaches the limit pressure.
When kernel is heated up, moisture inside of endosperm starts
to expand. Around 212 C, water-starch mix becomes gelatinous
form. When heat increases, water vaporizes and very high pressure
is created inside of kernel. As it explodes, steam inside the kernel is
released. The soft starch inside the popcorn becomes inflated and
spills out, cooling immediately and forming into the odd shape we
know and love. A kernel will swell 40-50 times its original size. Now
you know the adventure of a corn kernel which you can tell your
friends in a party!

Nobel prizes are awarded every year since 1901, as Alfred Nobel
bequeathed in 1871. According to Nobel’s will, each year Nobel
prices are given to best invention or project that have most benefits
for humanity and that make humanity takes steps further. In this
edition of SCI, we present you Nobel winners of 2013, in physics,
chemistry and physiology or medicine.
In physics The Nobel Prize in Physics 2013 was awarded jointly to François
Englert and Peter W. Higgs ‘for the theoretical discovery of a
mechanism that contributes to our understanding of the origin of
mass of subatomic particles, and which recently was confirmed
through the discovery of the predicted fundamental particle, by the
ATLAS and CMS experiments at CERN's Large Hadron Collider’.
In chemistry The Nobel Prize in Chemistry 2013 was awarded jointly to
Martin Karplus, Michael Levitt and Arieh Warshel ‘for the
development of multiscale models for complex chemical systems’.
In Physiology or Medicine
The Nobel Prize in Physiology or Medicine 2013 was awarded
jointly to James E. Rothman, Randy W. Schekman and Thomas C.
Südhof ‘for their discoveries of machinery regulating vesicle
traffic, a major transport system in our cells’.
