But heat can also be produced by the friction of liquids, in which there could be no question of changes in structure, or of the liberation of latent heat.

We were then satisfied that, with proper lubrication and better adjustments, a little more power could be expected. The completion of the motor according to drawing was, therefore, proceeded with at once.

Performing is very much like cooking: putting it all together, raising the temperature.

Heat can also be produced by the impact of imperfectly elastic bodies as well as by friction. This is the case, for instance, when we produce fire by striking flint against steel, or when an iron bar is worked for some time by powerful blows of the hammer.

I've learned from experience that if you work harder at it, and apply more energy and time to it, and more consistency, you get a better result. It comes from the work.

There is a construct in computer programming called 'the infinite loop' which enables a computer to do what no other physical machine can do - to operate in perpetuity without tiring. In the same way it doesn't know exhaustion, it doesn't know when it's wrong and it can keep doing the wrong thing over and over without tiring.

As the temperature drops, the need for heating oil goes up.

It's the constant and determined effort that breaks down all resistance, sweeps away all obstacles.

Few ideas work on the first try. Iteration is key to innovation.

Whenever the work is itself light, it becomes necessary, in order to economize time, to increase the velocity.
