I was already a fan of the original manga, but the first episode of the Jaadugar anime is not only visually stunning, it also portrays, through wonderfully nuanced and compelling characters, how deeply Islamic civilization has valued knowledge and intellect. I was truly moved.

I found out my girlfriend was lying about one guy.

For months, she kept saying he was just a friend, and honestly I believed it enough to not make it a daily issue. Not fully, but enough.

You know that weird place where something feels off, but you also don't want to become that insecure person who questions every name?

Then one night, her phone was on the table and his notification came.

“Reached home?”

That message alone was not proof of anything. People can ask that. Friends can ask that. I was still trying to be normal about it.

But then I remembered she told me she was out with her cousins.

So I asked casually, “Who dropped you?”

She said, “My cousin.”

I asked which cousin.

She paused.

That pause did more damage than the message.

After that, the story started changing as she spoke. First it was cousins. Then it was cousins and friends. Then he was there too, but only for a while.

Then it became, “Actually, he dropped me because it was late.” Then somehow I became insecure for even asking.

Bro, I was literally watching the probability update in real time. The notification changed it a little. Then the pause changed it even more.

By the time the story changed for the third time, the calculation was basically done.

That is Bayes theorem.

Bayes theorem is what happens when you start with a belief, observe new evidence, and update that belief.

Formula:
P(H | E) = (P(E | H) × P(H)) / P(E)

Where:
- H: Hypothesis
- E: Event (what you observe)
- P(H): Prior probability
- P(E): Overall probability of event
- P(E|H): Prob. of event if hypothesis was true
- P(H|E): Probability hypothesis is true given event (updated belief)

Let's take an example and solve it step by step:

Suppose your girlfriend is honest 95% of the time and lies 5% of the time. She avoids eye contact 30% of the time when she is honest and 80% of the time when she is lying.

If she avoids eye contact, find the probability that she is lying.

Step 1: Define Hypotheses
- H1: She is honest
- H2: She is lying

Step 2: Define Event
- Event (E) = She avoids eye contact

Step 3: Write Priors
- P(H1) = 0.95 (honest)
- P(H2) = 0.05 (lying)

Step 4: Write the Likelihoods

Avoids eye contact when honest
- P(E | H1) = 0.30

Avoids eye contact when lying
- P(E | H2) = 0.80

Step 5: Calculate the Total Probability

P(E) = P(E|H1)×P(H1) + P(E|H2)×P(H2)
P(E) = (0.30)(0.95) + (0.80)(0.05)
P(E) = 0.285 + 0.04
P(E) = 0.325

Step 6: Apply Bayes Theorem
- P(H2 | E) = (P(E | H2) × P(H2)) / P(E)
- P(H2 | E) = ((0.80)(0.05)) / 0.325
- P(H2 | E) = 0.123

Final Answer:
If she avoids eye contact, the probability that she is lying is 12.3%.

Congratulations, you have just learned Bayes theorem!

I’ve been learning pygame this weekend. Reading docs and writing code.

Let me tell you, nothing nothing nothing comes close to changing a line and tabbing to see your changes. Slowly seeing your code turn into something. Calling a new function and seeing something appear on the screen…

Prompting will never.

Not saying we should go back. I won’t. Just realizing how much I loved this.

Today marks a month since I've started actively learning Urdu, so I've decided to celebrate with a verse by Manish Shukla: “It did not just teach us eloquence, Urdu taught us excellence itself”

This was my 1st time trying calligraphy in Urdu with ink and a brush! 🫢😄
