A single-dish radio telescope is usually an antenna shaped as a parabola that collects the radio waves from a celestial object and focuses them onto a receiver. The signal received is then electronically processed so that it can be stored and analysed by a computer. The telescope has to have two important characteristics to be really effective and allow one to detect faint and distant celestial objects: it should have a large collecting area (large telescopes can collect more electromagnetic waves and therefore detect fainter objects) and the resolution (how close things can be together and still be distinguished as separate) should be as good as possible. The high resolution is a very important point for radio astronomy. A big telescope can better separate objects that are close together. However, size in meters is not the whole story: the diameter of the telescope should also be many times (as many as possible!) greater than the wavelength of the radiation it detects. In other words, the longer the wavelength of the radiation that we radio astronomers want to receive, the larger the telescope has to be in order to have the same resolution. An optical telescope with a diameter of 10 cm already gives the best resolution obtainable from the ground due to the effect of the atmosphere: such a telescope gives a resolution of about 1 arcsec which means it will be able to separate two people 1 meter apart at the distance from Groningen to Amsterdam (about 200 km). On the other hand, a parabola of 30 metre (quite typical for a single-dish radio telescope) will separate the two people only if they are 60 metre apart. So to get the same resolution as obtained from the optical telescope we need a parabola of more than 1 km: something that is impossible to build with the current technology! This has been a big limitation for single-dish radio telescopes and they are at most the size of 100 m (with the exception of the 300 m antenna in Arecibo, that, however, being built in a valley cannot move and can track objects only over a small part of the sky). For a long time, at the beginning of radio astronomy, this was the main limitation: it was not possible to obtain information about celestial objects comparable to what the optical telescopes were getting. In particular, it was very difficult to identify which object in the sky seen by optical telescopes was actually emitting radio emission, because the resolution of the radio telescopes was so poor.

Flipping someone off because one of their coworkers wronged you a month ago is an act of unprovoked aggression. I would consider it part of a police officer’s job to at least investigate someone who makes such an act. It’s a fuzzy line. On the one hand, free speech doesn’t absolve you from the consequences of your actions. On the other hand, the police can’t respond the same way a civilian would while on duty. So I don’t blame them for trying to go through proper channels (as much as possible) to retaliate.

25 pounds is not that heavy and you shouldn't have a problem with the drywall. I would drill 2 holes and put toggle anchors in them, then screws. Leave the screws out from the wall enough that you can hang the wire from the mirror over them.
A mirror really would not affect the experiment much unless the liquid is colored. Color absorbs light and emits the energy as heat. If you want something to evaporate faster, try using some dark colored, non-reactive surface.
lol the music at the end is funny
sir, i didnt think a one single person can be too smart, you are a gift sir
You will have to save up for a better one, most telescopes under $100 dollars are crap . If you want to learn about the right one for a higher but not too pricey one contact me from my profile , my email is either listed there or on my website.
