If it disagrees with experiment it is wrong.

In general we look for a new law by the following process. First we guess it. Then we compute the consequences of the guess to see what would be implied if this law that we guessed is right. Then we compare the result of the computation to nature, with experiment or experience, compare it directly with observation, to see if it works. If it disagrees with experiment it is wrong. In that simple statement is the key to science. It does not make any difference how beautiful your guess is. It does not make any difference how smart you are, who made the guess, or what his name is – if it disagrees with experiment it is wrong.

— Richard Feynman

Thoughts from the ride

Two thoughts from the ride in this morning:

  1. If you want to tell where a car is going (perpendicular to you like at an intersection; parallel to you like driving ahead and possibly merging lanes), the best way to do so is by looking at their wheels. It gives you more accurate relative markings.

    If a car is at an intersection and rolls forward, you’ll notice their tire rotating before you can see the car moving relative to, let’s say, a stop sign or light post.

    If a car is traveling ahead of you and is merging, you’ll notice their tire moving relative to the road lines before you notice that the car body has moved towards you.

  2. Young people tend to accept the following statement more quickly than older people: the world is no more violent or crazy or _____ than it used to be, you’re just more aware of it due to the better spread of information (like the Internet, 24-hour news, etc).
