Gavran's latest activity

Isaac Newton was a great physicist, and he was also a great mathematician, which made him more independent than Albert Einstein. My...

Thanks, Gavron. These simple examples are very nice.

There is an isomorphism between the field of complex numbers and a specific set of 2x2 real matrices where a complex number ## a+bi ##...

The way to determine ##(a,b)## uniquely is to pick an angle ##\phi##. Then we have ##b=2tan(\phi)## and ##a=4/tan(\phi)##. As ##\phi##...

All right. Based on post #19, there are the next steps. $$...

There are an infinite number of solutions but for each one there is a different angle and thus a different triangle. I meant for a given...

I suppose that you use the Pythagorean theorem here. (see below) $$ \sqrt{(a+2)^2+(b+4)^2}=\sqrt{b^2+2^2}+\sqrt{a^2+4^2}\implies0=0 $$...

Newton was a lot more influential but that was just luck because he was first. As someone said, "the order of the Universe can only be...

Thank you very much .Scott, haruspex, Gavran

And what is your answer? Einstein or Newton? Please choose one, not both of them.

When we speak about electrostatic induction, we speak in the context of charges of regions of the object, not in the context of charges...

Newton His work was the groundwork for later discoveries.

I remember this local disaster https://en.wikipedia.org/wiki/Big_Blue_crane_collapse

Top three: Chernobyl, the Bhopal Disaster, and the Titanic.

What about the escalator failure in Italy in 2018? Football fans of a Russian team took the escalator going down. Without warning it...
