Calvin and the Brilliant Team.

It is nice to know that the strength of the brilliant team has increased. But...Calvin, is that the same you or has there been a mistake? Well, as far as i can see (analyse) the dimples in the smiles, and many other features matches. so, i think it is likely you (i m not so sure). I am sorry if this might appear to be a useless post. But i have heard there has been studies going on in the field of computer science related to face recognition using ANNs. I was wondering if someone could throw more light into the matter.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Yes, this is one of the most difficult and challenging problems in the field of contemporary mathematics. To find out which is the real Calvin! Me and my advanced research team have put years into this problem, and here's what we've done so far:

Let $C_1$ and $C_2$ be the condition that two pictures of "Calvin" are indeed him. Because we are solving a systems with two variables and we have two options, $P(C_1)=P(C_2)=50$ percent, since it is $C_1 \oplus C_2$ with equal probability. But we have to account for the probability that $C_1 \wedge C_2$ could exist. Based on the personality assessment that my team has performed on Calvin, $P(\neg (C_1, C_2))$ is approximately $11.452$ . By an analysis using topological surfaces performed on his face, there are some things to point out:

$C_1$ and $C_2$ have different glasses, raising the likelihood that neither $C_1, C_2$ occur.
Similarly, a scan of $C_1$ and $C_2$ 's eyebrows reveals slight differences.
$C_2$ is completely shaven, whereas $C_1$ is less so.
Most noticeably, their haircuts differ by a large factor.

The results are staggering. Our conclusion: $\boxed{\text{Both Calvins are the same!}}$ ! It's incredible! The math challenge master truly is himself! :O

Sad to say, the passing years have changed me outwardly. With the shift to San Francisco, I've gotten more tan due to exposure to the cruel sun. My failing eyesight also requires the yearly renewal of eye-wear prescription, and I no longer sport the trendy half-rim glasses. Alas, my hair which used to offer protection against the frigid winters of Chicago are not a nuisance, so I had it cut.

But inside, some part of me is always going to be a 15 year old.

A 15 year old who plays Diablo?

So, do you possess some part of yours which is always going to be a 5 year old ? If yes, then what's that ?

And you still look frickin boss.
