The TED’s viewers are amongst the first people who see that icredible tool. This touchscreen allows to have multiple point of contact at the same time, which means you can use your both hands to do few things at the same time.
He showes an application, which enables you to see the picture the way you want. It permits you to move, zoom, rotate, grab and stretch a photo very easily. It is fantastic.
Jeff Han showes other applications, for instance WorldWind. It is a program with a great interface made by NASA, wchich allows you to see ”all the Word” in 3D.
Personally, I like new technology and I am very keen on it hence I up-date my knowledge about new discoveries every day. I look forwad to brand new findings being aware that technology changes all the time and wonder what revelations will occur in few years time.

It’s all about looking on what’s the most likely thing to happen, dependences between hits and misses, just like psychics or palmers use only hits, and – who would guess – our psyche. We have a tendency to see faces, everywhere. You can see Virgin Mary even in cheese sandwich and sell it for almost 30 000$ on eBay. Yep, that’s US, so sad…
But the best part is when it comes to manipulate your mind. When you get evil, sinister lyrics about Satan, you will hear that ”hidden message” in backward recorded song. Why? You will try to notice every single word. It’s not a magic…
There’s much more of this, that’s why it should be seen by everyone, not only UFO or “the Simpsons” fans.
Steve said that no one had ever escaped death and it’s true. So everybody should live his own life, not someone’s else and no one should live with the results of other people thinking. We should listen our heart, intuition, our own inner voice. And everything in order to, as years ago wrote Thoreau, not to discover, when we come to die, that we have not lived.
Stay hungry. Stay foolish. I understand these words as encouragement to discovering every day something new, to enjoying our lives and every time wanting more and more because we can do it.

Andrea Ghez is a stargazing detective, tracking the visible and invisible forces lurking in the vastness of interstellar space.
She told about black hole.
First question was about supermassive black hole, second – interactive black hole on environment, and mainly is it exist.
Black hole is simple objects with three characteristic thing which can be describe: the spin, the mass, the charge.
Black hole of more than 4 million solar masses is located near region in the center of our own Milky Way galaxy.
The Schwarzschild radius is now known to be the radius of the event horizon of a non-rotating black hole.
When the star had exploded, produced lots of energy. Form is supernova. Sometimes some part of star collapse and is forming black hole. We can convert the gravitation energy. And we now know black hole exist.
A black hole's mass becomes entirely compressed into a region with zero volume. It zero-volume, infinitely dense region at the center of a black hole is called a gravitational singularity.
She also said that technology (telescopes) make easier to know galaxies ( and black holes too).

Most sound around us is accidental and unpleasant. There are four major ways sound is affecting us all the time.
First is physiological. The example is the sound of a loud alarm clock, which makes our organism to produce cortisol (fight/flight hormone).
The second is psychological, because music and natural sounds are the most powerful forms of sound that effects our emotional state, like classical music or birds chirping.
The third is cognitively, because we can’t understand two people speaking at the same time. That’s why the office noise makes our productivity 66% lower.
The fourth is behaviorally. We move away from unpleasant sound and towards pleasant sounds. The sound of jakehammer annoys us and for people who work with that noise, it is also demanding for their health. Also on sales music is very important because it can make us leave the shop fasters or turn around the door.
Music is powerful, because we recognize it fast and associate it. Many brands uses their brand sounds properly, like Nokia Tune which is played about 1,8 billion times a day. And what is brilliant – it cost Nokia nothing.
