It’s sad how much of what is taught in school is useless to over 99% of the population.

There are literally math concepts taught in high school and middle school that are only used in extremely specialized fields or that are even so outdated they aren’t used anymore!

Hi! Maths and celestial mechanics student here! 😊

I’m looking for more studyblrs to follow!

I’m an astrophysics student. I’m most interested in physics/astronomy/math. I also love books, plants, the beach, and pretty landscapes a lot. And of course I love nice stationery and pens. (These pretty much encompass what my posts are about.)

So reblog this if you are a also studyblr or are also interested in any of those things and I can check your blog out!!

And I don’t need your permission to defend the North.

Circling the Sun (larger)

friday the 24th of may 2019

hi! i have a week of break now yay and i’ll be less active here sorry

but here’s a pic that i took a month ago when i was studying for chemistry while we were in usa for a road trip!!

RESONANCES! They affect everything!

Our Sun's Mysterious 11-Year Cycle Appears to Be Driven by Alignment of The Planets

"This could help us better predict our Sun's giant, violent outbursts: a good thing, considering they have the potential to affect our life here on Earth."

Every 11 years, the Sun cycles through from riotous flare and sunspot activity to a quieter period, before ramping up again. It’s almost as regular as clockwork, and for years astronomers have been wondering what causes it. Now, they’ve proposed a new solution.

Even though the Solar System’s planets are much smaller than the Sun, the gravity of some of them is able to influence our star’s magnetic field. This, the researchers assert, is what controls the solar cycle.

Venus, Earth, and Jupiter assert a small gravitational tug on the Sun as they orbit it. The result is comparable to the way the Moon’s gravity influences Earth’s tides, producing a regularly timed ebb and flow.

The team has traced back 1,000 years of solar cycles, between the years 1000 and 2009 CE, comparing that data against the movements of the planets in that time. They found an impressively strong link between the two.

“There is an astonishingly high level of concordance: what we see is complete parallelism with the planets over the course of 90 cycles,” said physicist Frank Stefani of the Helmholtz-Zentrum Dresden-Rossendorf in Germany.

“Everything points to a clocked process.”

What the team found is that the tidal forces are strongest when Earth, Venus, and Jupiter align, and that this alignment occurs every 11.07 years - falling at the same time as the solar minimum.

Mythbusters Physics: Relative Velocity

The Mythbusters tested what would happen if a ball was shot at 60 mph off the back of a truck travelling at 60 mph to see what would happen.

It became a perfect example of the relative nature of physics - showing that velocity can vectorially add together. 60 mph in one direction cancels the 60 mph in the other, meaning a net velocity of zero.
