Neil deGrasse Tyson Quotes

What is cooking? 'Cooking' is a loose term. It's understanding energy or the lack thereof.

Last year, I made a refrigerator in my basement. And I needed to because I needed to figure how - you know there is no such thing as 'cold.' There is only less heat.

Whatever is not an energy source, is an energy sink.

When air is hot, the molecules move fast and they have high kinetic energy. The colder the molecules are, the smaller their velocities are and, subsequently, their energy. Temperature is simply a way to characterize the energy of a system.

What appeared to the earlier physicists to be the constant quantity of heat is nothing more than the whole motive power of the motion of heat, which remains constant so long as it is not transformed into other forms of work, or results afresh from them.

The older view of the nature of heat was that it is a substance, very fine and imponderable indeed, but indestructible, and unchangeable in quantity, which is an essential fundamental property of all matter.

Whenever we warm our hands by the fire, we allow the energy radiated by the fire to quicken up the movements of the atoms of which the hands are composed. When we cool any substance, we check those movements.

Sunlight provides the greatest source of renewable energy on the planet. Sunlight provides more energy in a single day, than we use in a year the world over.

Humanity stands ... before a great problem of finding new raw materials and new sources of energy that shall never become exhausted. In the meantime we must not waste what we have, but must leave as much as possible for coming generations.

The forces of steam, gravity, galvanism, light, magnets, wind, fire, serve us day by day, and cost us nothing.

The only way we can hope to combat climate change, protect our precious land and water, and prevent future extreme weather disasters is to cut the carbon pollution that’s warming our planet, and replace dirty energy sources with clean, renewable sources.

I leaned in science class that everything that generates light generates a little bit of heat, but not everything that generates head generates light. So it is with journalism.

Electrons are the carriers for electricity, but they are also carriers for thermal energy. This means thermal conductivity is increased when the carrier density is increased.

Weather systems are natural heat engines, and like all other heat engines, both natural and artificial, they are driven not by temperature per se, but by differences in temperature between one location and another.

There's a reason why Europeans take siesta in the middle of the day. It's not just because it's hot, but because it doesn't feel good to be outside or look at light when it's coming straight down overhead.

I am a creature of the sun. I don't ever mind being in the heat.

The sun. I hate the sun.

At least, the sun had the decency to stay the hell away from us.

An Ant on a hot stove-lid runs faster than an Ant on a cold one. Who wouldn't?

Heat is a universal solvent, melting out of things their power of resistance, and sucking away and removing their natural strength with its fiery exhalations so that they grow soft, and hence weak, under its glow.

The elevator shaft was a kind of heat sink. Hot food was cold by the time it arrived. Cold food got colder. No one knew what would happen to ice cream, but it would probably involve some rewriting of the laws of thermodynamics.

We have this handy fusion reactor in the sky called the sun, you don't have to do anything, it just works. It shows up every day.

I think pretty much all people who love each other had some kind of thing at first sight. I mean, there has to be some kind of moment where you, like, feel a different energy around someone.

Yet now the industrialized world is moving away from fossil fuels and moving towards renewable sources of energy. And because we have not invested so much into education, we don't have the technology and sometimes we don't even have the capital to buy this technology.

Enthusiasm imparts itself magnetically and fuses all into one happy and harmonious unity of feeling and sentiment.
