Starting today August 7th, 2024, in order to post in the Married Couples, Courting Couples, or Singles forums, you will not be allowed to post if you have your Marital status designated as private. Announcements will be made in the respective forums as well but please note that if yours is currently listed as Private, you will need to submit a ticket in the Support Area to have yours changed.
Then do it outside, next to a large building where you can gauge the distance (perhaps in how many bricks or stories the ball flies up). Chalnoth is right in that the tennis ball will fly up very far, farther than you might think.-- I'm not allowed to bounce a basketball in the house.
Favourite: particle physics
Least favourite: electromagnetism and electronics. Those blasted resistors!
This is what would happen:

Well, you basically need two things:Wow!
That was awesome!
So to get that level of concentrated energy from the sun, do you need one giant lens of unhappiness or could it also be possible by chaining a bunch of smaller ones together like I posted in my previous question?
Cheers WC!
Mirrors have lower losses.How so?
Could you explain?
They're probably modes for entering data. "Stat" may be a way to enter data by telling the calculator that, instead of doing sums, numbers entered will be stored for later use. Then, you can tell the calculator to bring up the mean (or mode, or S.D., or w/e) of the stored data.I have just bouth a basic scientific calculator. What are the "stat" and "verif" modes for? Its a Casio fx-83GT PLUS btw. Any old links will do. I would like to learn how to use the thing.

Here is a good link to read: Encyclopedia of Laser Physics and Technology - focal length, dioptric power, curved mirror, lens equation, microscope, photographic objective, focus, beam radius
I don't believe any material could possibly support its own weight and still be large enough for its gravity to be noticeable.Could God really have made the Earth flat?
Well, if you wanted as much gravity as the Earth has now, and we imagine that it had the same density as the Earth, it would have to be a little over 4000km, or about 2500 miles thick.If so, how thick would the planet be so that we didn't fly away because of the low gravity?
Depends on how much interference he has with the world. If he made the universe with the same physical laws, but intervenes to keep the Earth from breaking like a soggy biscuit, then sure.Could God really have made the Earth flat?
Let us assume for arguments sake that God did make the Earth flat; This could easily be verified just by moving towards the horizon till you meet with the edge. But like you were told by another poster; gravity cannot allow for a flat earth at Earth mass and densities.Could God really have made the Earth flat?
If so, how thick would the planet be so that we didn't fly away because of the low gravity?
Naturally, this is one of my less weirder questions.
Would it be possible to build an intensely concentrated PSI air bomb of unhappiness?
No chemicals. No toxins. Very low manufacturing and costs.
In today's new age of compassion, this just seems like it would be the more politically correct and nicer way of killing people.
So how close would this be theoretically possible on a large scale?
Cheers my fellow physics genuses (sp?)!
I really meant no nitro, C4, uranium, gun powder, etc. when I said no chemicals.
Touche on beating me with philosophy PGP.
Not without chemicals, no. It would basically have to be some sort of mood-altering drug that depresses people. There is no way to have any significant, accurate influence on peoples' minds without some sort of physical contact, either through some sort of chemical or direct manipulation of the brain (pressure on certain areas of the brain can do all sorts of things, though that generally requires cutting open the skull...).Would it be possible to build an intensely concentrated PSI air bomb of unhappiness?
