Head Canon that it takes months for Mark Watney to stop narrating everything that he is doing. And most of that is peppered with generous profanity.

“Now I am going to cleanse myself with precious precious water. Fuck you Mars!”

The crew indulges him for a while but eventually starts saying, “Fuck you Mars!” as a general phrase of discontent.

The coffeemaker jams? “Fuck you Mars!”
Someone stubs a toe? “Fuck you Mars!”

NASA is not amused when tshirts and bumperstickers pop up.

When I was 17 my appendix ruptured because I thought I was just having period cramps and didn’t go to the hospital so don’t tell me PMS symptoms are no big deal

one-lastmiracle

this actually happened to me during my math final and i didn’t think anything of it and when i was later admitted to the hospital my math prof was asking me ‘you didn’t have to take the final! why didn’t you tell me it hurt?!?!’ and i told him i’ve had cramps worse.

he gave me 100

This is actually an extremely common occurrence simply because in sex ed they don’t teach you how to tell the difference between menstrual cramps and other more serious pains. The way to tell the difference between cramps and appendicitis is that while menstrual cramps are generalized toward the middle of the stomach below the belly button, pain from a swollen or burst appendix will start in the middle of the stomach and relocate to only the lower right side, even lower than menstrual cramps, and is a very localized pain. It also comes on extremely suddenly and will worsen over time or when you make a sudden movement, like a cough or a sneeze.

Basically, if you’re feeling any sort of pain, even if it’s menstrual cramps, don’t hesitate to tell the school nurse or a parent, or if you’re out of school and home even make a doctor’s appointment. Chances are if your cramps are that bad there’s something they can do to improve that as well.

I am boosting the shit out of that reply, because I am twenty-fucking-five years old and did not know how to tell the two pains apart

Adding another diagnostic tool! This is something we use in the ER called the rebound test. Basically, appendicitis and cramps react differently to certain things. If you’re still not sure if you have cramps or appendicitis, take two fingers and press them into your abdomen where the pain is (try repeating this on the lower right quadrant of the abdomen just to be sure.)

When you press in firmly, it will probably hurt. Here’s the test: LET GO. Does it get better or get worse? Appendicitis will immediately hurt worse when you let go. Cramps will not. Go to the ER if the rebound test makes it worse!

THE REBOUND TEST IS REALLY IMPORTANT.

My husband got sent home from the ER with a rupturing appendix. When he came back and was rushed into surgery, the surgeon was super angry – “Why didn’t anyone do the rebound test?!”

All great info, but there is another lesson to be learned here: if you’re in major pain, it’s probably important - so don’t let anyone tell you it’s not. There is a documented pattern of women who go to the ER with complaints of pain being dismissed as overreacting…when in reality women have an incredibly high tolerance for pain, to the point that some don’t even realize exactly how serious their condition is. These stories only serve to illustrate this point.

Every time I see this..

^the women have a high pain tolerance thing…my orthopedic surgeon, the first day I met him laid me down and messed with my shoulder. At this point I had been told by doctors and another orthopedic surgeon I was overreacting and making my pain up…for months. There were days I missed class because I couldn’t get dressed. Anyways, he laid me down and messed with my shoulder. When he was done he helped me sit up, and went and sat down across the room from me. He looked me dead in the eye and said “I just dislocated your shoulder, put it back in, and you didn’t flinch. You needed surgery four months ago.” He was pissed. Seriously, don’t take major pains lightly, in the abdomen or otherwise.

coolest physics thing that u know??

fyphysica answered:

The coolest physics thing that I know keeps changing over time. But here is one that is extremely fascinating ( and also exaggerated for the effect ; but true! ):


Person living at the top of a skyscraper experiences time faster than one at the bottom

It is a known fact that the higher you are in the earth’s ** atmosphere, the lesser the effect of gravity is.

But the lesser the effect of gravity is, the faster the time ticks.

image

By how much you ask? Even if you live on the top floor of the Burj Khalifa  your entire life, you would have aged more only by a few milliseconds than your friends at the bottom. 

( Sure, doesn’t seem like much, but hell would break loose if we don’t consider this on the bigger scale of things )

This is known as Gravitational time dilation and is at the foundations of General Theory of Relativity. (More about this in an upcoming post)

Have a great day and thanks for asking!


EDIT: ** Lets just say hypothetically the earth is not spinning( just to ignore special relativistic effects) and we are looking at only the effects of height.

Corollary - 1 : If your backyard has a black hole, then you would experience time slower than your neighbors.

image

Since the gravitational field around a black hole is much much stronger than earth, time starts to tick slower and slower for you than for your neighbor as you near a black hole.


Corollary - 2 : If you push your neighbor into a black hole, you have to wait literally forever to watch your neighbor fall into it, says GR. (Sublte to explain here, but covered in upcoming post)

Corollary - 3 : You cannot get bored while doing Special and General Relativity. There are always crazy scenarios to explore!

Have a great day!

So, our physics teacher has the strange idea of motivating his students by letting each of us present a physical phenomenal we find interesting to our classmates in a 5-minutes-presentation. And now I need something that is interesting for everyone - even people that usually don't care for physics -, but has interesting facts for someone who's interested in it, too (preferably with an easy experiment). You don't happen to have any ideas, do you?

fyphysica answered:

First of all, your professor is awesome for taking the time to do this. Of the top of my mind, the best one I have is Chladni figures.

image

Basically take a flat metal plate, fix it at the center and spray some fine sand particles on it.

Using a violin bow, gently excite any edge of the plate to magically witness these beautiful normal mode patterns ( known as Chladni patterns/figures ) forming on the plate.

image

Also notice that by pinching the plate at different points, the pattern obtained changes.

image

There is a whole lot of physics that goes behind such a simple phenomenon and I dare say we understand it completely. There are lots of questions on these figures that we have no answer for!

Hope this helps with your presentation. Have a good one!

The war of the storms

Place: Jupiter

Years: 1997 - 2000

Summary: Around 1997, there were three great storms named FA, DE and BC on Jupiter. Then DE got jealous that BC was getting all the attention from Earthlings and went on a vortex attack ,destroyed it and ascended the throne as BE.

When FA came to know about what had happened, it summoned all the gases and went on a full out attack on BE to become BA

TL;DR:

DE + BC —> BE ;

BE + FA —> BA ;

( True story ! )

Automatica

Okay I am not sure how many of you are aware of Nigel Stanford’s work. Here is a teaser from one of his upcoming albums - Automatica.

As an engineer and a music lover, this is one single I am eagerly waiting for.


Cymatics

One of the many reasons why I love his work is because of the immense effort he puts into it and how he effortlessly blends so many engineering and physics concepts into a single video.

This is one of his famous videos titled Cymatics:

To understand why Nigel Stanford’s video is transformative to an intellectually thriving audience, let’s just do a simple breakdown on the concepts that a 6 minute video of his encapsulates:

Faraday waves, Faraday Instability, Ruben’s tube, Chladni plates, Vibrational analysis, Resonant modes Tesla coils, Ferrofluids, Playing around with Frame rates of a camera, Droplet Dynamics, Plasma lamps, and so much more…

I have seen this video so many times and it is a gold mine of exotic visual displays of physical phenomenon.

Kudos Nigel Stanford for this amazing work. Bow in respect sir !


** Complete breakdown of this video in an upcoming post :)
