Shout-out to this guy for pausing in the middle of doing his eyeliner to question fluid mechanics
trick or treat :v ?
starting off strong with a tr-
TRIIICK
MATHEMATICS IN YOUR STEM DEGREEEEEE
I was taking my fluids final today and this image popped into my head and I laughed aloud in the fucking exam and it is now 2am and I can’t sleep because of how ridiculous that is
Thursday, June 8th || Finals day 5/7
Trying to push through to my fluids final. The thing about having an exam on the last day of the year is that most of my friends are already home, and campus is weirdly empty. It’s kinda peaceful though.
Really looking forward to moving out of my dorm and into my house tomorrow afternoon.
The majority of the physical phenomena on this planet can be captured by first and second order differential equations. It is rare for a third order differential equation to show its face. Thus in according to this mathematical observation we find its correlate in the fact that we can have a wave in the water corresponding to a first-order differential equation, and a wave written on that wave corresponding to a second order differential equation. On normal shorelines one never witnesses a wave within a wave within a wave, which physical situation corresponds to a third order differential equation.
But such was the velocity of wind within the narrow channel that separates mainland Davao from Samal Island, wind so vicious it threatened to topple me over as i stood on the jetty jutting into the channel, that the water was worked up into fine wrinkles (see the upper left corner of the first photograph) , these wrinkles placed onto a wave within a wave, corresponding to that magical third order differential equation.
Water finds it difficult to fold itself more than twice, surface tension tending to smooth out wrinkles; yet here it managed to accomplish the minor marine miracle of folding itself thrice, wild wind wrinkling the waters, no other word than "wrinkle" sufficing to describe this fine liquid rumpling.
This was the first time i had seen "wrinkled water", the experience an epiphany, the wild wind bringing about the derivative of the derivative of the derivative; the wild wind allowing the water to express its existential essence more completely.

Is ketchup a solid or a liquid ?
Solid
Liquid
If you didn't have a clear answer, if you got confused for a second, it's normal. It's because it's neither. Ketchup is what is called a Bingham fluid (or yield fluid) that act as a solid unless a certain stress is applied to it. It is a very fun and interesting physics phenomenom. Fluids like ketchup are still studied today. But that's not my main point.
My main point is that, for a lot of people, science that goes beyound high school book, science that is currently studied sounds like something very far away. People are studying quantum mechanics or black holes or things like that. And don't make me wrong, some are and it's very important and interesting.
And then there is ketchup.
Ketchup that we all saw. That a lot of us have in our kitchen. Ketchup that goes beyond the idea of solid and liquid.
Sometimes, science is so mundane and I love it.
reviewing fluid mechanics ⋆ ˚。⋆
I have a fluids exam monday, so I will be thoroughly studying for the next two days. i have thurs/friday off, so im going to study now to enjoy my long weekend. then i’ll review with my study group sunday evening ;)
