Acceleration and deceleration are the same thing. There is no time variable in the equation. Acceleration is the velocity. Reverse the equation m x a = F

The sole purpose of language is communication. There is no such thing as proper pronunciation. There is no governmental body or international organization that set rules or standards for how words are pronounced. Names of people should be pronounced however the name holder wants. The only...

Some things cannot be said in "normal language" and can only be understood if one learns the language of science which IS mathematics. On can make statements that are mathematically correct but have no relationship with the universe at large. As to black holes direct observations of what occurs...

Objects exist even when they are not " looked at. " In quantum systems the only way to get information about quantum particles is to make a measurement or to look at them.

Interesting. Einstein is reported as having once said " If you can't explain it to a six year old, you don't understand it." Mathematics is no more special than any other creation of the human imagination. The universe does not calculate, does not use mathematics, yet everything seems...

It is not known. Nor can it be known until you receive information from it. Quantum objects do not exist until they interact with other objects and cause a change in objects we are observing. The momentum, spin, charge, are unknown to the entire universe and are shared only through interaction...

Much ado about nothing. Math is not physics. A set of equations is not physics, it is math. The math is used to describe everything that exists, i.e. can be observed. Do some observed objects obey the PLA? If so then PLA has a physical meaning. Meanings are a much harder subject.

An interesting thread. I have no math skills and am an avid fan. In my opinion many of the posts describing information were wide of the OP. The information the OP asks about exists only in the system to be measured. It has nothing to do with knowledge that an experimenter will gain, or probable...

You guys are waaayyy over thinking this. I am asking how bright is the surface of the moon and what size/power/wattage light bulb comes closest to that. I am curious because of all the Apollo hoaxers that use crap about shadows and how the bottoms of the lander is too bright. I want to be able...

Thanks for all of the replies. My question was poorly worded I'll try again. If I were on the moon and looked at my feet I would perceive a certain brightness. If i could shrink my self to the size of an ant and stand on a light bulb what wattage would the light need to be to produce the same...

If the moon were a light bulb how many watts would it be.

Mobile devices especially smartphones are toys. Designed to deliver consumables in the form of of data and and candy bars. The screen size makes them very limited in their ability to display information. Their connectivity limits there use as a reliable communication device. If you have to many...

Thanks but does not the fact that there is a change in the state of the detector tell you the location of the electron? Is this not true of all such experiments regardless of what attribute you are trying to measure? When there is a change in the detector you know where the electron is and when...

A single electron is fired at a detector, what do we know about the electron after it reaches the detector that we did not know before.

still crazy after all these years
