Neil deGrasse Tyson Quotes

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.

Do not great Bodies conserve their heat the longest, their parts heating one another, and may not great dense and fix'd Bodies, when heated beyond a certain degree, emit Light so copiously, as by the Emission and Re-action of its Light, and the Reflexions and Refractions of its Rays within its Pores to grow still hotter, till it comes to a certain period of heat, such as is that of the Sun?

In this house, we obey the laws of thermodynamics!

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.

I have the thermometer in my mouth and I am listening to it all the time.

The laws of thermodynamic s are such that if the water is getting warmer - and I believe it is - the energy of the weather is going to go up.

There's so much energy exchange [in conduction], so you get back a lot, of course, but you also have to give a lot. It's kind of high-energy thing.

Human ingenuity has given centuries to the goal of ensuring that the human body might move around at an even 68 degrees all year.

For myself and my loved ones, I want the heat, which comes at the speed of light. I don't want to have to hang about for the blast, which idles along at the speed of sound.

Nature prefers the more probable states to the less probable because in nature processes take place in the direction of greater probability. Heat goes from a body at higher temperature to a body at lower temperature because the state of equal temperature distribution is more probable than a state of unequal temperature distribution.

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.

Nothing changes instantaneously: in a gradually heating bathtub you'd be boiled to death before you knew it.

According to the kinetic theory of gases, the mean kinetic energy of a molecule is a measure of absolute temperature.

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.

The weird thing about the arrow of time is that it's not to be found in the underlying laws of physics. It's not there. So it's a feature of the universe we see, but not a feature of the laws of the individual particles. So the arrow of time is built on top of whatever local laws of physics apply.

Something can be real - actually existing, not merely illusory - and yet not be fundamental. Scientists used to think that heat, for example, was a fluidlike substance called 'caloric' that flowed from hot objects to colder ones.

If we assume there is no maximum possible entropy for the universe, then any state can be a state of low entropy.

When I was studying at Purdue, we learned our thermodynamics from an antique steam engine. When I went back in 1964, I found the laboratories packed with the most modern equipment for the study of thermodynamics, some of which had been built by the students themselves.

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.

I shot a lingerie campaign in Munich once during the winter, and it was actually snowing. At one point, my body literally turned blue, and we had to stop for 20 minutes to get my temperature back to normal. I kept telling myself, 'Try not think about the cold,' but that's extremely hard when you feel like your toes are about to fall off.

Copper is a superb cooking metal, conducting heat so evenly it has unparalleled control, especially at low temperatures.

[Referring to Fourier's mathematical theory of the conduction of heat] ... Fourier's great mathematical poem.

A certain fire pretends to be alive; it awakens. Working its way along the hand as a conductor, it reaches the support and engulfs it; then a leaping spark closes the circle it was to trace, coming back to the eye and beyond.

Living fire begets cold, impotent ash.
