# You Might Be A Mathematician If......

1. You are fascinated by the equation $e^{i \pi} + 1 = 0$.

2. You know by heart the first fifty digits of $\pi$

3. You have tried to prove Fermat's Last Theorem.

4. You know ten ways to prove Pythagoras' Theorem.

5. Your telephone number is the sum of two prime numbers.

6. You have calculated that the World Series actually diverges.

7. You are sure that differential equations are very useful tool.

8. You comment to your wife or girl friend/ boy friend that her/his hair is nice and parallel.

9. When you say to a car dealer, "I'll take the red car or the blue one," you must add " but not both of them."

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.

My phone number isn't the sum of two prime numbers. It is a prime number.

So, you've memorised a ten digit prime

@Amrita Roychowdhury you too. Q

- 5 years, 9 months ago

Well, I disagree with you, sorry!

- 5 years, 9 months ago

Nice compilation , I must say!

Well for me , I think it's :

• Yes for 3,4,5,7

• No for 1,2,6,9

But I really don't mind what the criteria is , I know I am a great fan of Mathematics !!

- 5 years, 9 months ago

1 is true for me. No for the rest 8.

- 5 years, 9 months ago

I have sign(s) -

• 1,
• 2 (partially),
• 3,
• 4 (one can easily find a new method, so I guess I have > 10 methods),
• 5 (that's very near to Goldbach's Conjecture),
• 7 (but it depends in what manner are you taking them to be useful tools)

And I don't have sign(s) -

• 6 because I'm not all familiar with World Series (I'll google it out),
• 8 because I still don't have any girlfriend,
• 9 because I never went to a car dealer

Are these enough signs to come to any conclusion???

- 5 years, 9 months ago

1. Yes
2. No, forty
3. Yes
4. No
5. Yes, every 1 in 2 phone numbers is so.
6. I would if I knew what the World Series is.
7. Yes
8. No, but I had shown them that their phone number is a sum of two prime numbers.(Search 'A Late Night Conversation' on Brilliant)
9. No, I have never been to a car dealer

$5$. Are you sure?

- 5 years, 9 months ago

In our country, phone numbers are 10 digit numbers and the Goldbach conjecture has been verified upto 10^17

- 5 years, 9 months ago

No, Goldbach's Conjecture has been verified upto $4\times 10^{18}$ (as verified by Wikipedia).

And I wonder if someone in this world has got the number $3325581707333960528$?

You might be a mathematician if it's Year 2015, you can't help but devise a million math problems that involve the number 2015. Do a Brilliant search on "2015" and see what happens.

• Yes, definitely

• Yes, 51 :P

• Yes, foolishly though

• Nope, I know 3 or 4, maybe

• Nope, it is the sum of three primes

• Nope

• Yes, of course.

• Nope, I don't have any

• Nope, I've never talked to car dealer.

You know 51 digits of $\pi$, really?cool!

- 5 years, 2 months ago

Yeah, it is of no use though :P

- 5 years, 2 months ago

Thanks for crushing my every hope of being a mathematician. I will now hate you for the rest of my life.
