It's definitely higher than "11"

The world of energy is a confusing place. What's better, nuclear or solar? What's the difference between fluorescent bulbs and LEDs? What's the difference between energy and power? And what the heck is a kilowatt-hour?!

Is the science of Orphan Black realistic? Could we clone humans, or engineer them to have customized traits? We take a look at today's genetic engineering technologies to find out if designer babies and human cloning is, or should be, a reality.

His talk was given at a local TEDx event, produced independently of the TED Conferences. "The earth is flat". "Home computers are useless". "Humanity is condemned to be starved". "Women are born inferior". Throughout the years, pioneering scientific discoveries overturn established theories, vibrant societies transcend dominant perceptions, bold individuals expand physical and intellectual limits proving everything wrong: This is the way in which we seek to improve our lives and to deepen the understanding of the world around us. At TEDxLimassol we are searching for the next refute in small and large things: In the universe and subatomic particles. In our societies and in our bodies. In our behavior, attitudes and perceptions. In our mental, physical and personal capabilities. Proving everything wrong is always the right thing to do.

Rocket scientists incorporate a number of different testing techniques before committing a rocket to flight. One of those tests is called a "static test." In this setup a rocket engine is fired while being anchored to a test bench. Fitted with instrumentation, the scientist can safely measure thrust, pressure, cooling, and other rocket data. Watch and witness from inside the inferno when something goes wrong.

Is it all just make believe?

A weekly show where we endeavor to answer one of your big questions. This week, a bunch of people asked, "Why doesn't glue stick to the inside of the bottle?"

This is the solution to: http://youtu.be/QD3hbVG1yxM

How exactly does meditation affect your body?

Just how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world.

Counting stars from the shore of the cosmic ocean...

Could we stop an asteroid on a collision course for Earth?

Miss The Solar Eclipse This Year? Watch This Incredible Footage Of It!

A weekly show where we endeavour to answer one of your big questions. This week, "bored during school" asks, "Why do we get dark bags under our eyes when we're tired?"

One picture can change the world.

Only one side of the Moon is visible from Earth because the Moon rotates about its spin axis at the same rate that the Moon orbits the Earth, a situation known as synchronous rotation or tidal locking.

Science is delicious.

Solved with science for the sake of the human race!!

Optical illusions are images that seem to trick our minds into seeing something different from what they actually are. But how do they work? Nathan S. Jacobs walks us through a few common optical illusions and explains what these tricks of the eye can tell us about how our brains assemble visual information into the 3D world we see around us.

Why is a 'broken heart' so painful?

As more and more parents are choosing not to vaccinate their children or are vaccinating them later, diseases like measles are making a comeback. Are vaccines safe? How do they work? This week we look at why are people afraid of something that has saved so many lives, and look at the history and science of vaccines.
