No worries, I can help with that one. The prime factorization of 180 is 2² × 3² × 5.

It’s a pretty straightforward process. You just need to break the number down into a product of its prime factors. Remember, a prime number is a whole number greater than 1 that can only be divided by itself and 1.

Start by dividing 180 by the smallest prime number, which is 2. You get 90. Do it again, and you get 45. Now, 45 isn't divisible by 2, so try the next prime, 3. That gives you 15. Divide 15 by 3 again, and you’re left with 5. Since 5 is a prime, you're all done.

So, the prime factors are 2, 2, 3, 3, and 5. Easy peasy.

Einstein's special theory is having two main ideas. We call them postulates.

The first idea is simple. The laws of physics are same for everyone who is not accelerating. If you are on a smooth train moving at constant speed, and I am standing on the ground, physics is working same for both of us. This is called the Principle of Relativity.

The second idea is the strange part. The speed of light in a vacuum is always constant. It is same for all observers. It does not matter if you are moving, or the light source is moving. The speed of light is like a final speed limit for the universe.

These two simple ideas together are the foundation. They lead to big results like time slowing down.

He is widely believed to be living in Karachi, Pakistan. This is the official stance of both India and the United States. The UN has even listed addresses for him there. Pakistan, however, has consistently denied that he is present in their country, making his exact location unconfirmed.
