Hey @davenn, you really have an intriguing hobby! As many others have said earlier, I imagine it would be really amazing to hold something from space right in your hands! But I am wondering, how do you differentiate, how do you know that the rock you find or buy is really a meteorite? I have...

This all just shows how history tends to repeat itself. Lessons, as much as mistakes, are forgotten in just 2 generations, 80 years, and all the vices and evils come flooding back. Russians says that it is time to remind the West and Europe of what happens when red lines are crossed and refresh...

Wow. You guys are so smart... :bow:

Yes. Why?

The hypothenuse - I know. I also know all of the DC segment, however I am not sure what the DC-base side of the triangle is exactly. Do I? So, I can find a trick (is it not too hard? :)

Hello. I am wondering how I can find the area of a trapezoid from its two legs and bases. My problem: ABCD is a trapezium with AB parallel to CD such that AB = 5, BC = 3, CD = 10 and AD = 4. What is the area of ABCD? If we trace a straight line from A down parallel to the height of the...
