"Vince Reffet and Fred Fugen, members of the French BASE jumping team Soul Flyers, set a new world record after taking a dive off the top of the world's tallest building: Dubai's Burj Khalifa."

Wowza! My heart rate went up while watching this video. Can't even imagine what it'd be like to actually make a jump like that.

Tidal Forces

This illustrates how the Moon causes tides on the Earth.

The Moon’s gravity pulls on each piece of the Earth, but the attractive force is a little stronger on the side facing the Moon, and a little weaker on the side opposite the Moon.  The average force is the force at the center of the Earth.

The arrows at each point show how much the attractive force differs from the average as the Moon circles the Earth. These are the tidal forces, and the result is a bulge in the ocean on opposite sides of the Earth. Earth rotates under these bulges, resulting in about two high tides each 24 hours.

The definition extracted from Wikipedia:

The Pythagoras tree is a plane fractal constructed from squares. Invented by the Dutch mathematics teacher Albert E. Bosman in 1942,[1] it is named after the ancient Greek mathematician Pythagoras because each triple of touching squares encloses a right triangle, in a configuration traditionally used to depict the Pythagorean theorem. If the largest square has a size of L × L, the entire Pythagoras tree fits snugly inside a box of size 6L × 4L.[2][3] The finer details of the tree resemble the Lévy C curve.


The construction of the Pythagoras tree begins with a square. Upon this square are constructed two squares, each scaled down by a linear factor of ½√2, such that the corners of the squares coincide pairwise. The same procedure is then applied recursively to the two smaller squares, ad infinitum. The illustration below shows the first few iterations in the construction process

If the Wikipedia one was a bit hard to understand here's how I think of it:

Starting with a 3,4,5 right triangle, if you think of the sides of the triangle as each being one of the sides of a square, the areas of the two smaller squares add up to the area of the larger square.

Now thinking of the two smaller sides (in this case, 3 and 4) as being the bases of two other 3, 4, 5 right triangles. As long as the ratios are equivalent, a right triangle with sides 9/5,12/5,3 has the exact same angle and side ratios as a right triangle of sides 3,4,5, a right triangle with sides 12/5,16/5,4

The Pythagoras tree emerges by continuing this process many, many times (as needed). 

Each triangle is geometrically similar to the first as the angle-angle and side-side ratios are the same for each
The beauty of the fractal is that if you look at simply a single triangle and the three squares involved with said triangle, the "tree" (trunk as largest square and branches as two smaller squares) is basically the same as any other triangle-and-three-square figure in the whole fractal.

Thinking of Pythagorean Theorem in a physical sense was easy to understand by me

The area can be determined as follows

By Pythagorean theorem

S₁² + S₁² = L² 
2S₁² = L² 
S₁² = L²/2 
S₁ = L/√2 

S₂ = S₁/√2 = (L/√2)/√2 = L/(√2)² 
S₃ = S₂/√2 = (L/(√2)²)/√2 = L/(√2)³ 
S₄ = S₃/√2 = (L/(√2)³)/√2 = L/(√2)⁴ 
. . . 
Sn = L/(√2)ⁿ 

We start with 1 square 
In each iteration, we add twice the number of square added in previous iteration 

In iteration 1, we add 2 squares 
In iteration 2, we add 2*2 = 2² squares 
In iteration 3, we add 2*2² = 2³ squares 
In iteration 3, we add 2*2³ = 2⁴ squares 
. . . 
In iteration n, we add 2ⁿ squares 

So in each iteration, we add 2ⁿ squares, each with side length of L/(√2)ⁿ 
Area of all squares in iteration n 
= number of squares * area of each square 
= number of squares * (side length )² 
= 2ⁿ * (L/(√2)ⁿ)² 
= 2ⁿ * L²/2ⁿ 
= L² 
= Area of original square 

So why does Wikipedia get total area = 1? 
Because, they have obviously assumed that dimension of original square = 1 x 1, which means L = 1, therefore L² = 1. However, this is NOT explicitly stated in the link, which it should have been, since the last mention of original (i.e. largest) square assumes square of size L x L, not 1 x 1.

"Long before the birth of # Christ, the Jews celebrated an eight-day Festival of Lights, and it is believed that the Germanic peoples held a great festival not only at midsummer but also at the winter solstice, when they celebrated the birth of the sun and honored the great fertility gods Wotan and Freyja, Donar(Thor) and Freyr. Even after the Emperor Constantine (A.D. 306-337) declared Christianity to be Rome's official imperial religion, the evocation of light and fertility as an important component of pre-Christian midwinter celebrations could not be entirely suppressed. In year 274 the Roman Emperor Aurelian (A.D. 214-275) had established an official cult of the sun-god Mithras, declaring his birthday, December 25, a national holiday. The cult of #Mithras, the Aryan god of light, had spread from Persia through Asia Minor to Greece, Rome, and as far as the Germanic lands and Britain. Numerous ruins of his shrines still testify to the high regard in which this god was held, especially by the Roman legions, as a bringer of fertility, peace, and victory. So it was a clever move when in year A. D. 354, the Christian church under #Pope #Liberius(352-366) co-opted the birthday of Mithras and declared December 25 to be the birthday of Jesus Christ."
