   My speech in the Canadian Young Scientists Journal’s Lunch   

Science development is like a journey. It starts with a very simple idea, deep down in a hidden place between thoughts of a scientist.

Science is all about asking questions, but questions which can be tested, so a scientist has to generate testable questions from his thoughts. These questions can be answered by doing researches or performing a lab experiment.

                        

 The key idea is to communicate the science that the scientist has developed. The art of sharing science is like forming a ring in the chain of scientific development. Without sharing the information and results of research there is no use in making science.

 Science can be communicated with the use of lectures, books, internet websites, and journals. One of the most useful ways of communication is publishing a scientific journal.

Journals can not only benefit the readers but also the writers. The authors can learn from the feedback and comments that they receive from their readers about their writing. Also ‘the audience’ can learn from the journal. Most importantly, a science journal can start a new idea for another progress in science. That is how science works.

Having a scientific journal in high school level can be more beneficial in terms of educational purposes. First of all, students can use their idea and write their own paper. A journal is a motivation for students to work on science, and try to come up with a new idea. They can learn how to write in a scientific method and structure.  And most importantly, they benefit from the comment and reviews, so they can see their mistakes or how they can improve their work.

Finally, I would like to tell a story about how science journal and communication in scientist world is so important.

 Dr. Nafiseh was studying nutrition, and what kinds of food or vitamins the body makes use of. And while doing her research, she read a journal article about studies of deer and moose in the Northern Canadian forests. It said that during the winter there is no grass available, and these animals live by chewing some bark off trees.

 

Nafiseh realized this meant they could digest cellulose, which human beings cannot eat. She did experiments on what enzymes or chemicals allow cellulose to be broken down into food. And she wrote about it in a journal.

 

Some months later, a scientist in Germany read Nafiseh's article. He was working on biofuels. And the problem with biofuel was that we know how to distil food crops full of sugars and carbohydrates into the fuel. That meant that a lot of food crops, like corn and soybeans, were going to make biofuel. But that resulted in less food available for people to consume. So the price of food has been going up around the world.

 

The German scientist was wondering if we can use other kinds of plants for biofuel. Why can't we use grass, like the grass beside all our roadways? It's because we don't know a cheap way to break down cellulose into usable chemicals -- like the deer and moose are able to do.

 

This German scientist wrote a journal article. He didn't really have answers yet, but he called for scientists around the world to do further research on how to distil the cellulose found in plant cell walls of plants into chemicals usable for both fuel and food.

 

If this work leads to real results, we could see a vast increase in the types of plants and the amount of plants in the world, which we can use for both food and fuel. Research like this could provide a real answer to the world fuel shortage, and the food crisis. Think about the poor people around the world experiencing problems, wars, and hardships, which this research could help solve.

 

Scientific journals bring scientists and thinkers around the world closer to each other. They help people put pieces of puzzles together. When you do research and publish it in a journal, it gives people all over the world ways to use your thinking. It invites all those people to build on what you have done in solving the problem.

   Canada’s contributions to the study of our planet from near-Earth space   

Canada is one of the leading countries in the space and remote monitoring projects. These projects are being done by the Canadian Space Agency (CSA). The government of Canada created CSA to ensure that all Canadians learn and benefit from the innovations of space science and technology. “Its objectives are to support and promote a highly competitive space industry and address the needs of Canadian society. With almost half of Canada's GDP growth in the knowledge-intensive sectors of the economy, the Canadian Space Program is a key driver behind continued leadership on the world stage, new opportunities for industry and scientists, and long-term social and economic benefits for all Canadians”.  Since its creation in 1989, it has worked on many space projects and its advanced applications are being used now. For example, television broadcasting, weather forecasting, mobile communications, water purification, heart monitors, ultrasound scanners, laser surgery, resource mapping, navigation, protective clothing, advanced structural design, robotics, solar power, sewage treatment and even shock-absorbing athletic shoes are a short list of CSA’s research applications and their contributions to our daily lives.

CSA has done and has participated in many space-based and earth-based projects. Some of these recent outstanding projects are Phoenix Mission and International Space Station (ISS) and RADARSATs (one and two). ISS is a place where experiments and observations in the orbit around the earth are conducted. The main fields of research in ISS include biology (including biomedical research and biotechnology), physics (including fluid physics, materials science, and quantum physics), astronomy (including cosmology), and meteorology. Phoenix Lander is a recent successful Lander on Mar’s surface, which landed on May 25, 2008.

Space is a vast infinite place to be discovered, but it is also a good place to study earth from another perspective. Many satellites were sent to near-Earth space mainly for sighting the earth by CSA such as Constellation, SCISAT, ODIN, CLOUDSAT, ENVISAT, TERRA, UARS, VIKING, and RADARSATs (one and two).  Looking at the earth from space has many advantages. First, it is possible to see a broader picture of the earth. A satellite can take a picture of a whole continent in one shot. Satellites are faster in taking pictures than any other technology that exists today. For example, RADARSATs (I and II) rotate around the earth in a few hours, so they can provide data from a big part of the earth within a short time. They also update the data every time they revolute. It helps scientists study the changes in data. Study of these changes provides useful beneficial applications of satellites which have led to many discoveries. Observing the earth from space provides essential information which allows us to understand our atmosphere and land environments and how they interact with each other.

RADARSAT II uses very high tech devices and as a result can provide very accurate data. It is basically designed for looking at the earth from outer space. It can look at the glaciers and keep track of them. One other very important and useful application of this satellite is its ability of surveillance of agricultural fields and forests. It also has devices for making topographic maps which are useful for the study of heights and depths in deferent parts of the earth. It is the most advanced satellite in its kind. It has the new technology of using multi-polarization system cameras which have much higher resolution than the previous version (RADARSAT I) and any other satellite for this purpose. It also has a very fast communication speed with the earth which makes working with this satellite fast and simple. It is the fastest satellite in the world- in terms of communication. It has the ability of taking images in all the required angles since its high tech cameras can observe the light in any orientation. This multiple mode capability has made this satellite a unique device which can be used for many deferent research and surveillances and because of its property this satellite has many clients.

The cameras on the RASARSAT II are very useful to take pictures of field and crops. They can compare the changes in the data or in the pictures and investigate the fertility of soil in one area. This satellite has different cameras for different wavelengths. The best type of wave for agricultural purposes is a microwave. Only water in plants usually reflects this wavelength, as a result they can use this property of vegetation and take may useful pictures.

During an unexpected disaster they surely need some pictures to manage how they can deal with the consequences. For example in a flood or earthquake they can use those pictures to measure the damage that have occurred and figure out the best way to rescue the survivors. When oil spills into the ocean they can use wavelengths appropriate to take a picture of the infected area and they can easily get rid of the oils.

These pictures are also good to keep track of water flow, wind, and ice melting in the Arctic and pollution rate of the air. Each of these reflects and absorbs different wavelengths, so RADARSAT has to use different wavelengths to take pictures of them. Each wave has a different diffraction property and they diffract at different angles so the size of the pictures for each wavelength can vary.

Considering the financial aspect of this project, CSA and its sponsor spent millions of dollars to build and lunch RADARSAT II, it paid back with the service that this satellite can offer the researchers, navy, farmers and rescue teams in a disaster. RADARSAT II’s pictures can also be sold and this provides big financial profits.

In conclusion, Canada has an immense contribution in studying the earth from near-earth space. CSA has worked on lots of projects which are directly or indirectly improving our knowledge of the earth. RADARSAT II has been made mainly for looking at the earth and finding useful data about our planet. This satellite helps geologists learn about the earth’s features by making topographic maps. It helps scientists study the weather and air pollution concentrations in different parts of the world. These days global warming is a big issue, this satellite can keep track of ice melting in poles and glaciers and provide useful information about how we can stop the global warming. It can provide information about weather conditions, wind, water flow which are valuable for meteorologists and their researches about the earth’s weather and atmosphere. And more importantly it can save lives and help to reduce the destructions caused by disasters such as floods, hurricanes, oil spills and many others. Overall, the benefits of this satellite are numerous and it is one example of the many Canadian projects and Canada’s contribution in studying our planet.

   Bible of physics:   

The world is something like a great chess game being played by the gods. And we are observers of the game. We do not know what the rules of the game are; all we allowed to do is to watch the playing. Of course, if we watch long enough we may eventually catch on to a few of the rules. The rules of the game are what we mean by fundamental physics. Even if we knew every rule, however, we might not be able to understand why a particular move is made in the game, merely because it is to complicated and our minds are limited. If you play chess you must know that it is easy to learn all the rules, and yet it is often very hard to select the best move or to understand why a player moves as he does.

   God does not throw dice   

Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. Quantum theory says a lot, but does not really bring us any closer to the secret of the Old One. I, at any rate, am convinced that He (God) does not throw dice. (Albert Einstein, On Quantum Physics, Letter to Max Born, December 12, 1926)

   IF   

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:

If you can dream--and not make dreams your master,
If you can think--and not make thoughts your aim;
If you can meet with Triumph and Disaster
And treat those two impostors just the same;
If you can bear to hear the truth you've spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
And stoop and build 'em up with worn-out tools:

If you can make one heap of all your winnings
And risk it all on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breath a word about your loss;
If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: "Hold on!"

If you can talk with crowds and keep your virtue,
Or walk with kings--nor lose the common touch,
If neither foes nor loving friends can hurt you;
If all men count with you, but none too much,
If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son!

Rudyard Kipling (1865-1936)

   who cares about justice? Q :-(   

Justice! Can you taste justice? Can you smell equality? What do all your fancy words mean? I can’t live my life for things that I can’t taste, or smell, or hold in my hands. Soil after the rain, it has such a rich, sweet smell. And tamarind shoots leave a golden taste on your tongue. These things are real. These things I can live for.
