Quotes About Energy

A proton or neutron is made up of three quarks, one of each color. A proton contains two up quarks and one down quark; a neutron contains two down and one up.

famous equation, E = mc2. So, if there's

Mass: The quantity of matter in a body; its inertia, or resistance to acceleration.

Eventually, however, the star will run out of its hydrogen and other nuclear fuels. Paradoxically, the more fuel a star starts off with, the sooner it runs out. This is because the more massive the star is, the hotter it needs to be to balance its gravitational attraction.

It also meant that whenever a body is not acted on by any force, it will keep on moving in a straight line at the same speed.

Only light, or other waves that have no intrinsic mass, can move at the speed of light.

you remember every word in this book, your memory will have recorded about two million pieces of information: the order in your brain will have increased by about two million units. However, while you have been reading the book, you will have converted at least a thousand calories of ordered energy, in the form of food, into disordered energy, in the form of heat that you lose to the air around you by convection and sweat.

All the known particles in the universe can be divided into two groups: particles of spin ½, which make up the matter in the universe, and particles of spin 0, 1, and 2, which, as we shall see, give rise to forces between the matter particles.

Since we know the universe itself was once very small—perhaps smaller than a proton—this means something quite remarkable. It means the universe itself, in all its mind-boggling vastness and complexity, could simply have popped into existence without violating the known laws of nature. From that moment on, vast amounts of energy were released as space itself expanded—a place to store all the negative energy needed to balance the books.

How will we feed an ever-growing population? Provide clean water, generate renewable energy, prevent and cure disease and slow down global climate change? I hope that science and technology will provide the answers to these questions, but it will take people, human beings with knowledge and understanding, to implement these solutions.

So the total energy of the universe is zero.

according to the laws of nature concerning gravity and motion – laws that are among the oldest in science – space itself is a vast store of negative energy. Enough to ensure that everything adds up to zero.

Segunda ley de la termodinámica]. Según esta ley, el desorden o la entropía aumenta siempre con el tiempo. En otras palabras, se trata de una forma de la ley de Murphy: las cosas van a peor.

What is it that breathes fire into the equations and makes a universe for them to describe?

We were told that you can never get something for nothing. But now, after a lifetime of work, I think that actually you can get a whole universe for free.

This is easy. I would like to see the development of fusion power to give an unlimited supply of clean energy, and a switch to electric cars. Nuclear fusion would become a practical power source and would provide us with an inexhaustible supply of energy, without pollution or global warming.

The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materialise out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy.

any normal object is forever confined by relativity to move at speeds slower than the speed of light. Only light, or other waves that have no intrinsic mass, can move at the speed of light.

and energy, it would have taken an infinite amount of energy to get it there. For this reason, any normal object is forever confined by relativity to move at speeds slower than the speed of light.

The laws of physics demand the existence of something called 'negative energy'.

Mungkin saja ada antidunia dan antimanusia yang terbuat dari antizadah. Tapi kalau Anda bertemu anti-Anda, jangan berjabat tangan! Kalian berdua bakal lenyap menjadi kilatan cahaya.

Stephen Hawking

Deoarece principiul de incertitudine nu permite s? avem valori exacte atât pentru câmp, cât È™i pentru viteza lui de variaÈ›ie, spaÈ›iul nu e niciodat? gol. El poate avea o starea de energie minim?, numit? vid, dar acea stare e supus? la ceea ce numim fluctuaÈ›ii cuantice sau fluctuaÈ›ii ale vidului.

hey bitch, you're never too old to rock and roll
