The Anti-Gravity Board Illusion

@GrayGrantham57 @Lilly_22100 Je partage cet avis

@Lilly_22100 Don't know, but my guess would be the spring would collapse and all of the elastic potential energy stored in the expanded spring would transfer into increased downward force .

Which ball will touch the ground first?

@TonyBur87179224 @itsmyfeelingss_ @Lilly_22100 Indeed,is there energy transferred from the spring to the ball... ? I wonder whether this causes additional acceleration when the spring contracts toward the ball? In this case, it is likely that energy is transferred.

@itsmyfeelingss_ @Lilly_22100 A - because the recompressing spring would add to the downward force of gravity slapping A downward - B would just fall under gravity. Isn't the energy in A, Ball+spring; while that in B, is ball only. Please help me if i'm wrong.

@jamestanton A=ax/2 =by/2 =cz/2 ⇒ 1/a+1/b+1/c=P/(2A)=1/2 (P=A)CQFD

The 7-15-20 triangle has perimeter and area both of numerical value 42. If x, y, z are the three altitudes of the triangle, prove that 1/x + 1/y + 1/z equals the nice rational number 1/2.

@kaushik_sumit @jamestanton

@jamestanton Odd perimeters give more Δ pairs than even ones. Because the Δ inequality a < P/2 allows more integer solutions when P is odd with no half-integer symmetry to restrict combinations.

Today's Puzzle: There are 4 triangles with integer side lengths of perimeter 11, but only 3 of perimeter 12. Is the count of integer triangles of perimeter 2N always greater than the count of integer triangles of perimeter 2N+1?

@jamestanton oops 😊!!

@scodiu Try drawing a picture of each of the your suggested triangles. There is something curious afoot!

Today's Puzzle: One can make 4 triangles with integer side lengths and perimeter 11. How many such triangles can you make of perimeter 12?

Is it running forward or backward

@RAnForr784 @BholanathDutta FORTH?? My first programming language. I thought it was no longer in use!

@BholanathDutta Hi. Thanks for the puzzle. m = 12, m! = 479001600, using FORTH. :)

Let’s see how many get this right.

@MathType using Villani's theorem 21²+22²+23²+24²=25²+26²+27² demo: giacometti.free.fr/carres.html

Lagrange’s four-square theorem asserts that any positive whole number can be written as the sum of four squares of integers. Leave an example in the comments! #MathType #NumberTheory #math #mathematics #mathproblems #mathfacts

@mnd233445 The data is incorrect; we arrive at a contradiction after finding x = 36/7 and y = 36/7, which does not equal 18...

Shaded area = ?

@jamestanton toute ligne qui "pénètre" dans une figure doit en ressortir: d'où un nombre pair sauf si il y a tangence ;-)

If two congruent concave quadrilaterals meet an odd number of times, must it be because at least one of those point is a point of tangency?
