The presentation was made at the Hawking Radiation conference, which was co-hosted by the theoretical physics institute, Nordita, and the University of North Carolina, on the campus of KTH Royal Institute of Technology in Stockholm. Nordita is driven by both KTH and Stockholm University.

Scientists have used a high-speed camera to film hummingbirds' aerial acrobatics at 1000 frames per second. They can see, frame by frame, how neither wind nor rain stop these tiniest of birds from fueling up.

What is dark energy? What is dark matter? Well, if we knew exactly we would have a nobel prize - we know that they exist though. So what do we know about those strange things?

Holy moly I'm gonna tear my $100 bill into five and rearrange it and boom! I have $200.

Man and woman's best friend!

What was the procedure to launch a nuclear missile?

Will the crow defeat the puzzle?

Uranium is a unique element, used in research, medicine, space travel, and of course weapons.

Turn water into wine! This simple science experiment demonstrates how fluids with different density can switch places. Fun to use as a magic party trick or as a demonstration for a physics experiment. Watch as the water switches place with the wine, because water has a higher density then wine. You could try using a playing card instead of the thin plastic spacer.

We use a LOT of energy, but we waste a lot too. Where that waste happens might surprise, you though. We don't just waste energy when we leave the lights on or the thermostat cranked down too low. It happens at the dinner table and the water faucet as too!

Why do spikes form on ice cubes? Without them the world would be vastly different.

It's definitely higher than "11"

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?"
