Unsolved Mathematical facts

While investigating facts about Unsolved Mathematical, I found out little known, but curios details like:

Working out the area of the largest sofa that can be moved around an L shaped hallway still remains mathematically unsolved.

In 1900, a German mathematician outlined a list of 23 unsolved problems in mathematics that he hoped would be solved in the 20th century. As of 2015, only 10 have been answered.

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across. Here are 14 of the best facts about Unsolved Mathematical I managed to collect.

1. An unsolved problem in mathematics is about moving the largest possible couch around a given corner.

2. Grigori Perelman, a mathematician who in 2003 proved the Poincaré conjecture--a long unsolved problem in mathematics--and later declined the Fields Medal, $1M Clay Millennium Prize and other awards.

3. The oldest unsolved problem in mathematics is proving whether or not odd perfect numbers exist. Mathematicians have been trying to solve this problem for 2,300 years.

4. In 2012 Shinichi Mochizuki released a proof that claimed to solve abc conjecture -a hitherto unsolved mathematical problem- however, 4 years on only 4 mathematicians have been able to understand the proof.

5. A university math student arrived late to class one day and saw two "homework" problems written on the chalkboard. He solved them, not knowing they were actually two famous previously unsolved problems in mathematics. This true story helped form the basis of the movie 'Good Will Hunting.'

6. Mathematician Evariste Galois was also an active political revolutionary. He solved a 350 year old unsolved problem on polynomials, pioneered Group Theory and Galois Theory, made contribution to mathematical Analysis, all before dying at the age of 20..due to wounds suffered in a duel.

7. One of the greatest unsolved mathematical problems in human history is the Riemann hypothesis, which tries to explain where in the natural numbers (counting numbers) the primes will occur. Many believe the problem will never be solved, and you will get a prize of $1 million if you solve it.

8. In the year 2000 the Clay Mathematics Institute stated 7 millennium math problems and awards one million dollars to anyone that solves one. So far six remain unsolved.

9. Goldbach's conjecture, which states that "Every even integer greater than 2 can be expressed as the sum of two primes" is the oldest unsolved problem in Mathematics (Since 1742, i.e 257 years till now)

10. The Clay Mathematics Institute has a list of 7 unsolved problems and offers a $1 million prize for each problem solved.

What is true about unsolved mathematical?

You can easily fact check it by examining the linked well-known sources.

In 2000, the Clay Mathematics Institute stated seven unresolved mathematical problems. As of 2016, six of them remain unsolved and whoever solves any of them will receive a prize of US $1 million.

Vincent Van Gogh visually depicted turbulence, an incredibly complex (and still unsolved) mathematical principle in several paintings during a particularly chaotic time in his life. - source
