# Let's break it!

A professor in a desperate attempt to solve a problem bangs his head on the wall out of frustration.

Now, there are two outcomes possible:

• Either the wall will break

• The wall will remain intact

Student 1: Outcome 1 is good for professor.

Student 2: Outcome 2 is good for professor, the reason being that if the wall breaks then professor certainly had provided more force than there had been on the wall if professor failed to break the wall. As a direct consequence of Newton's Third Law of Motion, the professor should feels more force hence more pain when he breaks the wall.

Whom according to you is right? If you think Student 1 is right, disprove argument made by Student 2.

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.

The wall will remain intact.....Student 2 is correct in its postulate...

Outcome 2 is good because if the wall breaks then all the energy would go to wall and some energy will return to the head

Obviously student 1 is correct. Because , it will be too painful for him to feel any pain at that time, or he might be faint already.

either the wall will break or the professor's head either way its going to be painful so best way is not to bang his head

- 6 years, 10 months ago

either the wall breaks or his head breaks, so isn't it better for the wall to break?

The student two must be a nerd, If I talk with him my head will break open

- 6 years, 10 months ago

Maybe, the problem was how to crack open his head! And he finally solved it!

very nice.... hahahaha

If the wall remains intact, the professor will not have to pay for the damage, hence it is better for the professor :)

- 6 years, 10 months ago

I pity the wall... Poor thing!

- 6 years, 10 months ago

third argument- professor will have to leave problem solving for at least 1 month.why? his head will break, won't it?

- 6 years, 10 months ago

Ah, reminds me of all the head-banging I did. This is why phd = permanent head damage.
