Physiology & Medicine / Re: Do brains burn more calories when you're thinking?

« on: 15/10/2015 08:52:26 »

I think it has something to do with what you are thinking.
The thinking come from problem solving would burn more calories than those from other sample things.
For example, I usually like to entertain foolish ideas and there must hadn't burn any calories!

But look from the large magnetic field- universe, much powder make a powerful magnet.

Upstairs positive solution !

Maybe more danger in the use of this technology in actual life

There have biology living without light. Like some microorganism.

So, even our sun suddenly vanished, we will find another way to survive, although it will be a long process.

BUT! It's too much terrible!

Simply put, the ocean is closer to us.

At least, it has been realized in small electrical appliances such as mobile phone. We can believe it will be used in more areas.

Internal electrical activity, through chemical energy into electricity.

I believe I couldn't go for a space travel even if 50 years later. It still be a very few people's activities.

Physics, Astronomy & Cosmology / Re: Gliese 581d

« on: 10/03/2015 06:49:44 »

Gliese 581 is about 20 light-years away from Earth, so it's a pretty "close" neighbor (by astronomical standards).
The planets have been detected because they wobble the star. But even our best telescopes can't actually see the planet because of the glare from the parent star.

There is a proposal to launch a space telescope called Starshade, which would block the light of the central star, allowing imaging of the planets around the star. If the planet is bright enough, it should be possible to collect a spectrum, and identify if it has an atmosphere, and what are the main chemicals in it.

That might give us some hints that life-as-we-know-it may exist on a planet. But the most likely way to detect intelligent life may be by detecting some form of communication, such as SETI is attempting.

It would be more to prove the existence of the planet if this way can be successful.

It's thought to be too hot due to a runaway greenhouse effect like that on Venus.

Too hot? It's said that there are rivers and mountains, I think the  temperature is appropriate.

« on: 09/03/2015 06:40:45 »

If solar panels were put in space, sent the energy produced back to earth would just be a waste of resources.  Maybe we can use these energy in the space such as provide the energy needed to power a spaceship, like an energy supply site.

« on: 26/02/2015 07:21:01 »

It's just part of life becomes faster. There are many other things we need to do, and more people won't spend on the smartphones too much time. Our brains have been running in order to live or work or study or any other things.

General Science / Re: How can I mention my spirit ?

« on: 15/02/2015 06:58:22 »

Since I started go to work, I always feeling very sleepy. But as soon as I finish my work, I would be very excited to do anything. Maybe I get the symptom of working with sleepy?

What does this have to do with mentioning your spirit?

Or another way,  how to keep me away from sleepy?
