Ok, i know this is kinda a dumb question, but what is the purpose of water towers? do they actually hold water? if so, y do they have to be in the air? if they don't hold water, then what is in them? yes, this is a random and stupid question, but i've always wondered.

And if yes do you believe that they can be explained as hot air balloons, weather phenomenon, or military experiments, or human-built aircraft of some kind?

Or do you think that they are space aliens possessing advanced technologies?

Or in full, which 4 people (incl the expert), living, deceased or fictional, would make a great 'Scrapheap Challenge' team?

My team would be:
R.J. Mitchell (designer of the Supermarine Spitfire)
Gordon Ramsay (for presentation and motivational purposes)
Darth Vader (who needs welding torches or an engine that works when you have the force!)
EXPERT: George "Hannibal" Peppard (Who else could turn a lawnmower and an old fridge into an armored tank?)

What volume in cubic centimeters would be occupied by 7.96 kg of osmium? The density of osmium (the densest metal) is 22.57 g/cm3?
Units are important! 7.96 kilograms- but density is given in grams per centimeters cubed...

We tend to consider as real the stuff to which the laws apply. For example, because we have laws for space-time, we feel that space-time is real stuff. Science does not reject subjectivity, but the laws of nature are the laws of the objective world from which somehow emerges subjectivity. In that sense, subjectivity is not real.

In this objective view of the reality, we cannot have a direct access to the laws of nature. We can only have formula and eventually build a technology to use them. However, these formula change when physics progresses. They are getting more and more accurate. The laws that are eternal are not accessible. They are part of the subjective world, a concept.

I believe that the true laws are real stuff. They are about themselves and how they get expressed in the objective world. The unification of these laws is God, eternal, everywhere, omnipotent, just like the laws. Being in the subjective world, we can experience them as God directly in our consciousness

I need to find a relatively cost effective way to measure the wavelength of red LED lights. I need to test several to find their wavelength range, then purchase more red LEDs, and measure them so I can keep the ones that fall within my wavelength range, and discard the others. This is for a machine that picks up red light from a relatively specific range, and the LEDs on it currently have lost strength (many are from the early 90s, some even older). I need to replace the existing LEDs with others of compatible wavelength. Also, in keeping with my explanation, red LEDs with weakened strength would still have the same wavelength light, but less intensity, correct? Thank you very much to anyone who can help me out with this!

Hi,

Scientists say that energy is the capacity to perform work.
They also say that light, heat and voice are energies.
On the other hand, spiritualists and some scientists say that everything is energy.

So, energy is an impulsion.
Or, energy is something which is not matter.
Or, energy is the general name for everything.

Which one is true?

PLEASE DO NOT ANSWER WITH LINKS.

Thanks.

Any ideas why it is the way it is? With centigrade, it seems reasonable that someone would have chosen 2 significant temperatures (such as freezing point and boiling point of water) and assign nice round numbers to them. It's intuitive and common sense. Fahrenheit, however, is different. It seems to lack the simplicity, intuitiveness, and common sense of centigrade.

So, my question: why is the Fahrenheit scale the way it is? How is it derived?
