yeah science!!

(sorry i’m just watching bits and bobs from a camrip hence all these posts) i think it was some sort of a review of Dark World, idk if article or tumblr post and i’m definitely not taking credit, that said something about superhero movies that i haven’t forgotten since then: that we all know the superhero will win in the end, what makes for a good plot is to see what they will sacrifice in order to win.

and it makes so much sense when you contrast dark world and ragnarok. i said quite recently that the ending of dark world (read: boss fight in london) bores me. this article/review posed it as this: the main emotional loses of that movie had already happened, mostly with loki, but definitely with frigga too. the ending is nothing but running around throwing punches, and yeah, that includes the science bullshit they injected into it.

ragnarok is like the perfect example of how it works by adding the sacrifice. holy shit. the boss fight isn’t even too long or anything. but the stakes are there, visibly. and the sacrifice is MAJOR. the ending isn’t about “i punched harder than i thought i could”, it’s about “i saved what really mattered but gave up what had mattered all my life”.

(thor 1 depends on how you look at it - the sacrifice of the bifrost that will stop thor from seeing jane for a couple of years? eh. the sacrifice of full on fighting your brother on the other hand…. mmm)

honestly my biggest pet peeve in fic AND in canon is everyone forgetting that kara is more than just a musclehead with the emotional range of a puppy and is actually a refugee, with her entire culture and language and religion wiped out, everyone she’s ever met dead, not simply a human with powers but a Kryptonian, always.

Who comes from a family of universe-renowned scientists, and was considered a genius by the standards of the extremely technologically advanced society that aren’t simply american humans in a few thousand years but people who probably have very different brains–along with also being created via the Codex and genetic manipulation (so it’s probably phased out any junk DNA, or vestigial structures–so, Kara probably doesn’t actually have an appendix or wisdom teeth tbh). If Kara had actually lived her life on Krypton, there’s a very high chance she would have went into the Science guild tbh

Really, imagine if you had gone through the equivalent of a rigorous phD program, and then all of a sudden put in a kindergarten science class. In the comics Kara was about to become the youngest person on the Kryptonian science counsel, ever

Yeah, of course Kara’s going to be bored with Earth level science, those science fairs that Alex dragged her along to are, to her, probably rudimentary at best, wildly off the mark at worst (and really–she’s been told to keep hidden. Genius children make news, genius children are noticed. Alex probably had a bit more leeway as the daughter of two world renowned scientists, already noticed by her teachers to be gifted but kara’s already the new adopted kid with the funny accent and mannerisms in a small town. That would be the exact opposite of laying low).

Lena’s probably a better tactician than Kara–a life as a Luthor would be a constant practice in tactics, long term planning. She’s definitely a brilliant scientist, but out of the two of them? Kara’s probably better.

And honestly? Lena realizing just how brilliant Kara really is, a fully fleshed three dimensional character, would be such a better story than just pretending that kara is an idiot with maybe 3 emotions.

Part of what makes Kara such a compelling character is that she’s been through so much, has so much anger and rage and sorrow but still manages to be a light and inspiration for others, intelligent, someone with a gift with words, a genius–someone who thinks of herself–Kara Zor-El, the powerless Kryptonian–as ordinary, someone not yet worthwhile, but she wants to be. She defeated Myriad through her words, through her sincerity and optimism, simply as herself. As Astra said, Kara “has the heart of a hero,” regardless of powers.Her heart is what makes her a hero.

tl;dr: kara is more than just a “puppy” who is incapable of intelligent thought

coolest physics thing that u know??

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.

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.

The Giants of Earth

Aliens are too often depicted as very human-like. Bilateral symmetry, main sensory organs on the head, dexterous hands on arm-like appendages, etc. Even size is relatively close or averages to around human size. But when you look at our own world, humans are giants. Relatively few animals have mass comparable to or greater than humans. Our height is particularly astounding since we evolved bipedalism and adopted a vertical stance rather than one that’s more horizontal, which you see even in other bipedal animals like birds.

So what if the same holds true for humanity compared to aliens? There are many advantages to having a smaller body, after all: fewer necessary resources to live and grow, more stable stances if they walk on three or more legs, better adaptability to cataclysmic events, and many others. If the species comes from a world with higher gravity especially, being lower to the ground is far more preferable rather than spending a lot of energy fighting the higher gravity.

So when humanity arrives on the interstellar scene, how would a universe filled with (generally) smaller sentients react to the new giants?

Legend of Space Australia

Any culture, from primitive to civilised has legends and mythology. So it’s not out of the realms of possibility to imagine aliens having a mythology telling of ancient deities, world creation, or super-beings who did extraordinary things to impress or frighten the previously mentioned gods. 

But what about urban-legends? As the name implies it was something that evolved in urban areas (the more “civilised” areas) So doesn’t belong to a large portion of humanity. 

What if aliens don’t have an equivalent of an urban-legend? They may get the ideas of stories and fiction and when they hear about things like Slenderman, Polybius, the Japanese Split-Mouth Woman, or even the old popping candy and cola makes your insides explode. 
They ask “Are these stories? a fiction to teach some moral lesson, or entertain in some way” 
But there’s always those people who are like, “NO, they’re true! I knew a guy, who knew a guy that this happened to!” 
And the aliens are just like “WTF! is earth even real?!!” No wonder humans are so tough if they have to survive all this!

Why is 1+1 =2 ?

This might seem arbitrary to most people, even intuitive. But, This is one of the deepest questions to have been answered in the entirety of mathematics. 

In the thresholds of common day experience one might also find ‘things’ that do not seem to obey this proposition:

  • 1 drop of water + 1 drop of water = 1 drop of water.  1 + 1 = 1.
  • 1 cup of water + 1 cup of alcohol = about 1 ¾ cups of 100 proof alcohol.  So 1 + 1 = 1 ¾
  • 01 + 01 = 10 ( In binary )
  • 1+1 =0 ( Modular addition by 2 )
  • 1+1=11 ( concatenation of two strings )

But hey, 1 + 1 is 2. Conflicts arise due to improper usage of ‘1′, ‘+’ and ‘2′.

So, What does ‘1′, ‘+’ and ‘2′ mean?

Peanos axioms :

1) 1 is a natural number. *
2) Every natural number has a successor. *
3) No natural number has successor 1 (or 1 has no predecessor) *
4) Every natural number has a predecessor except for 1. *
5) You don’t need to know this one right now. * 

Defining Addition.

We define addition a+b, for a,b natural numbers, as follows:

If a is 1, then a + b is b’s successor. * 

Otherwise, a has a predecessor, denoted a’. Then, a+b equals the successor of a’ + b. * (Axiom 4) 

For example : 

3+2 = > successor ( 2+2 ) = > successor ( 1+2 ) = > successor( 2 ).

2 = > predecessor ( 3 ) = > predecessor ( 4 ) = > predecessor ( 5 ) .

Defining Equality.

If a is 1, and b is 1, then a = b is true.

If either a or b is 1, but the other is not, then a = b is false.

Otherwise, there exist a’ and b’, predecessors of a and b, respectively (Axiom 4). Then, if a’ = b’ is true, a = b is true, otherwise a = b is false.

The decimal number system and Arabic numerals are not part of this theory - they simply represent natural numbers. In any case, the successor of “1” is denoted “2”, the successor of “2” is denoted “3”, and so on. *

So given these definitions, it is clear that 1 + 1 = 2. 


The Russel and Whitehead proof.

Believe it or not, it took Mathematicians Russel and Whitehead hundreds of pages to get to this result in the Principia Mathematica. This is considered to be a more rigorous proof for the proposition.

Going down that road is something only a truly dedicated mathematician would dare to endure. 


Thanks for reading! Hope you enjoyed reading it as much as I enjoyed writing it.

Why is energy always quantized ?

You ask a very interesting question!

The fact that energy is quantized probably feels weird to you because you are looking at it from the real domain. We must expand our horizon to the Complex plane.


Energy is a continuous analytic function

When you move from one energy level to another, you are basically move from one Riemann surface to another and it is continuous !!!

Imagine it like those those swirling car parking places that go round and round. You get from one floor to the another rather smoothly right ?


BUT when you look at it from the outside, it feels as if you have jumped from one floor to the other, but in reality you just moved from one Reimann surface to another.

The same thing applies to energy as well.

I understand that’s a lot math. But I hope it helps :D

Everyone in the crew had a fallback plan in case shit went south. Michael would be an electrician, Jack always wanted to work in radio, and Gavin would be a cameraman on films. Jeremy mentioned something about how he went to school for animation and Ryan perked up and went “Hey, me too!”

When someone asks Trevor what his fallback plan was, he shrugs and goes “I got my degree in aerospace engineering” and everyone stops to look at him.

“Aerospace engineering?”

“Yeah.”

“Like… like rocket science?”

“Yeah.”

“You can make rockets and here you are, doing crime?”

“C'mon, when’s the last time NASA was funded? If anything, I made a completely reasonable career choice.”
