Physics for a Very Basic Beginner

PHYSICS FOR A VERY BASIC BEGINNER

FALL IN LOVE WITH PHYSICS
#fallinlove

Suppose…
...you are travelling in a bus, facing forward the direction of movement. It’s a bit crowded; however there’s some loose space for one beautiful girl (say boy if you are a girl) at a pillar a few feet forth of you. Now when you are having this thought of that attractive girl, the bus stops and she boards! She boards! Coincidence or what (the word ‘Coincidence’ comes important in physics some time when we are dealing with multiverse, btw. But, hey, she’s damn beautiful and you can’t be distracted to physics!), she comes to that spot before the pillar. She leans on the pillar, which makes her face backwards. Awwwwww, those pinky lips! You are having an uncontrollable crush. You step forward, nearer and nearer. Swing your head forth, and both your lips meet.
Now, if the driver kicks for a sudden brake, you kiss her, and when she reacts bad, blame PHYSICS! Shout out ‘NEWTON!’ Blame INERTIA!!!

Okay, so that was just some fun!

PS: not entertained to be tried ;)

Physics is SEXY! Fall in love with Physics!
Make her your girlfriend.

Enjoy!!


The Must-knows for a Beginner

What really is she?
Of course, it's a branch of science. It studies natural phenomena.
Any matter (nowadays, antimatter as well) under rest or motion, can be studied under physics.

Professionally speaking, it deals with the behaviour of anything under motion or rest in space and time.

What makes her more interesting than other branches of science?
Because, the universe (probably multiverse) is infinite and mysterious, and she deals with it!
Physics has tons of mysteries yet to be answered! And that's where I wanna see myself as well as yourself tomorrow - with those mysteries, solving them, which eventually likely creates more mysteries!!

Four basic concepts for you
  1. Laws of motion
  2. Electromagnetics
  3. Relativity and gravitation
  4. Thermodynamics

Laws of Motion
  1. Inertia
  2. F = ma
  3. Every action has an equal and opposite reaction.

Electromagnetics
At least these points regarding light-
  • Light is an electromagnetic wave.
  • It travels in a straight line.
  • Its speed is constant (some recent experiments show that its speed varies with structure, though)
  • Its particles are called photons.

Relativity
Briefing it for a beginner: it is due to relativity that a person in idle travelling in a bus doesn't seem to have motion wrt his surroundings (the bus), but he is in motion as for you who see him from the ground.
Everything is relative!
For you, the earth seems still, but wrt the Sun, it moves.

In 1900s Einstein propounds his Special Relativity theory, and the whole concept of relativity was expanded. It was he, who stated the absolute speed limit for light (yes, you know that! Learned just a few minutes ago).

❗ Now as you know this much, know something crazy: run at jet speed with light, and the speed of light will be same. As if to make it the same, time slows down!
‘You serious??!!’ Obviously! Well, not obvious uh… Check out inertia’s update on Time Dilation.

Thermodynamics
The stuff related to heat and energy-exchange

We have four basic laws here: from the zeroth to the third!! Physics really is weird.


And… the Quantum Theory…?? You a beginner, right?
Well, have a simple try at inertia’s update on Quantum Physics. Before we end, one question: can you buy one and half packet of Dairy Milk Silk from a store? Or should you go by one packet, or else two, three etc? Well… that’s a bit of quantum physics for us.

Time Dilation Explained!

Image
T IME D ILATION You hear people saying ‘time slows down’ or ‘time speeds up’; ‘You can travel back into your past’ or ‘you can time travel to your future’ and blah blah time time. Or you might have seen the movie Interstellar and was like ‘Ohh! No way! That’s not possible’ or ‘But how?’ or ‘No, he can’t get younger than his daughter!’ You wanna know how? I shall tell you. The thing is, when you travel faster, time slows down for you. Time is relative. As beautifully explained by Einstein, for a man sitting with a pretty girl, an hour seems like a minute, and for him sitting on a hot stove, a minute seems more than an hour. It is a fact! Can’t accept it? Consider, a photon trapped perpendicularly in between two parallel mirrors. It bounces off from one to the other, continuously. alt="time dilation explained for anyone" The yellow dot is the photon, and its motion is depicted by the arrowheads. ‘d’ is the distance travelled by the photon from one mirror t

Alien Life - Where are our eyes?

Life outside Earth We have been thinking of life outside earth since time immemorial. And when it comes to the scientific search of extraterrestrial life, what and where are we searching for? The primary question - what , is thought worthy.  We assume that the Life outside Earth is like the Life on Earth. We assume the life to be water-based and to share many such similarities. Why so? Life outside could be of any form. It really need not be water based. It really need not have the needs of the terrestrial life, say, oxygen. But, it is easier to look for life with this assumption, for, as the old joke goes, the old man who lost his keys at night will search for it under the streetlights. So, although we know that life on Earth could not be representative of life elsewhere, we take up the assumption while we scout for extraterrestrial life. A similar approach is also usually taken while we decide where to hunt for life. We look for Sun-like stars and Earth-like orbits and temperatures,

Gravitational Waves: when black holes are Mittu aunt's Ladoos!!

Image
Suppose…     ...you have two ladoos in hand. You weighed each and found one 8 and the other 12 grams. Now, you want a bigger ladoo from those two and, wuhooo!, here I am with a glowing bulb over my head and helping hands. You hand them over to me, and I crush them both and mould the crumps of both ladoos together making a bigger ladoo for you. But, as you weigh the bigger ladoo I just made, you find it to be 17 gram. 12 + 8 = ???! Haa, yes, there arises a question on the missing 3 gram! So, what yeh gonna do? Huh! Blame me?? Nah, I didn’t - I didn’t eat it. Okay, so what’s the matter? Consider these ladoos to be black holes . Yeah, I mean it. Such a case was found with black holes as well. It was found that two black holes of solar masses 36 and 29, collapsed not to form a black hole of 36 + 29 = 65 solar mass, but of 62 solar mass. The missing 3 solar mass here went into the production of gravitational waves. And, that was the birth of gravitational waves . Not just
