Archimedes
In 213 BC in the city state of Syracuse, a genius named Archimedes lived. When the Romans tried to invade Syracuse, Archimedes’ inventions were used t
o defeat the Romans…for a time at least.
When the Roman fleet approached Syracuse, legend says that Archimedes was able to set fire to the fleet using large mirrors (bronze shields) to direct concentrated light towards the ships.
This two-part documentary demonstrates some of Archimedes’ inventions, and shows that they could have worked (as for example the mirrors destroying the Roman fleet.) The pressure of war forced the Greeks to be inventive. They were at the cutting edge of military technology. And Archimedes led the entire crop with his inventions.

Making Antimatter
If you had one ounce of antimatter, and if you annihilate it with one ounce of ordinary matter, it would give you an amount of energy equivalent to on
e million tons of rocket fuel. Anti-matter is being made by human beings; right now at a US government lab outside Chicago. Fermi Lab is home to experiments in controlling antimatter. Its mission is to do high-energy physics research. High energy physics research tries to understand the forces of nature at the smallest distance scales, which require the subatomic particles to go very very fast. Fermi Lab operates one of the world’s highest energy particle accelerators, called the tevatron. With this, scientists make particles of anti-matter.

History of Hacking
Steve Wozniak, John Draper and Kevin Mitnick are considered to be the pioneers of hacking. Wozniak (co-founder of Apple) and John Draper were not crim
inals, per se. It was Kevin Mitnick who turned it into a criminal enterprise. “It’s about forbidden knowledge. It’s about pranksterism.”
Hacking had two meanings. Its first meaning was “a guy who used to sit all night long on a borrowed computer, trying to devise the ultimate computer.” Eventually, however, the term – and the activity – morphed into that of setting out to “hack into” other people’s computers, and destroy the programs within. It began with “phone freaks,” people who took up the technical challenge of figuring out to call long-distance for free. That same kind of innovation and desire to meet the technical challenge extended to computers.

Are We Real?
Of all the wonders of creation, life is the most mysterious, and of all creatures, we are the most special. Surely there has to be a reason. Religion
offers a simple explanation: God created everything and only God knows why we are here. Science came to a different conclusion. It found no evidence for a “grand plan.” Yet recent discoveries have made scientists think again. Every religion has its own creation story. From God making the universe in six days, to an endless cycle of universes created from dead ones, to the whole universe being created in a single divine breath. There is one idea underpinning all these stories – human beings have a special place in this universe. We are here for a purpose. As scientists investigated our origins, however, they found that there was no need for a creator, and our special place in the universe was… not so special.

Age of Biotechnology
Biotechnology is improving the human condition – healing, fueling, and feeding the world. Any new technology, when first introduced, causes some conce
rns – either health, environment or religious, and all of them have some basis in fact. Will the technology be safe? Advocates of biotechnology (genetically modified crops) are pointing out that as more products get available in the market, more people will accept without concern or complain, that the products were produced by genetic modification of plants or animals. Take the cause of feeding the world, for example. Biotechnology is working on producing crops that can be grown in such locations as sub-Saharan Africa, which has little water and is currently a desert. Biotechnology can and will improve the quality of life globally.

Rapid Microbial Detection
Environmental pathogens are micro-organisms that normally spend a substantial part of their life outside of hosts. But when they are introduced to hum
ans, they frequently cause disease. Pathogens are carried in the water, soil, air, food and other parts of the environment, and can affect almost everyone. Microbes make the world go round. They are part of our bodies and part of the environment. They are an essential part of making things work. For example, in our guts, bacteria digest the material and enable us to survive. But from time to time these bacteria can become pathogenic and cause diseases. Current pathogen detection technologies are relatively slow and expensive. Samples must be gathered, then returned to a laboratory for testing. It can take from 24 to 48 hours for results. There is a need for quickly and efficiently measuring bacterial and microbial contaminants in the environment. Rapid detection of pathogens will lead to great improvement in world health.

Mind Science
The brain has a never-ending ability to change. Neuroplasticity is the brain’s extraordinary ability to change, grow and even rewire itself.
Bu
ddhist monks are willing participants in a study to discover the connection between the mind and the brain. Looking inward has become a way of life for Buddhist monks, and meditation is one tool in their quest for enlightenment. Buddhist monks have spent the last five years volunteering for a study, in which their brains were studied – in which scientists are studying how the monk’s mental training changes the brain.
The study tests how physical training and experience can alter brain circuits. They are investigating whether meditation can change the brain’s way of dealing with emotion.

Science of Cricket
At the heart of the game of cricket is the duel between a batsman and a bowler. A fast bowler can send the ball at fantastic speeds – too fast for the
human brain to react to. The ball seems to defy the laws of physics.
This documentary answers a variety of topics. How does the ball swing? How can science help fast bowlers bowl faster. How to make a bat for a world class batsman and what it takes to be a world class player.
Googlie, yorker, cutter, golden duck, these are just a few of the terms used in cricket. Games can last for days. It demands the stamina of an athlete, the flexibility of a gymnast, and the mind of a chess grandmaster. But at its heart, it is a battle between a batsman and a bowler.

How Visual Effects Work?
Visual effects in a movie are a composite of many different pieces of software, and typically each piece is provided by a different specialist.
It all starts on a green screen. Place markers are set on spots where the special effects will be added. First an actor is filmed walking through a scene, or acting in a scene, which is filmed in RealViz MatchMover Pro. Then, a 3D model replaces the actor, and rough composites of the special effects are made, in such software as Cinema 4D. Then the compositing is done in Apple’s Shake.

Get Smart
The human mind is perhaps the final frontier in our understanding of ourselves. How does our mind learn about the world around us? Every waking second
, our mind is at work learning about the world around us. But our capacity to learn is even greater than we think. By discovering how our mind works, we can improve our learning power and unlock our true potential.
Learning something new means rearranging the way our brain works. Our brain has a hundred billion neurons, or brain cells, all connected together. Learning is about creating and strengthening pathways through these neurons for impulses of electricity. But between each and every connection in our brains there is a tiny gap, called a synapse. For any of us to learn something new, the electrical signal has to jump across this gap to continue its journey.
