Easy way to find the centre of the board if it’s not an even number.

Papyrus of Ahmose or Mathematical Rhind (1500 BC / 1550 BC) is the oldest manuscript written in Algebra and Trigonometry.

Manuscript shows that Egyptians used first-order equations and solved them in several ways.

They know quadratic equations and solve them. They also know numerical and geometric sequences and know quadratic equations like two :

X2 + y2 = 100,

Y = 3/4 x, where x = 8, y = 6,

This equation is the origin of Pythagoras theorem, a2 = b 2 + c 2, and Egyptians used to call unknown number (koom).

Pythagoras developed his mathematical theories after travelling to Egypt and learning from Egyptian priests.

This has been proven in books of Greek historians and scholars such as Farpharius of Sour, Herodotus, and Thales.

Egyptians had Algebra, Trigonometry, and Geometry about 2000 years before the birth of Pythagoras and about 3000 years prior to al-Khwarizmi being born.

The Rhind Mathematical Papyrus (RMP; also designated as papyrus British Museum 10057 and pBM 10058) is one of the best known examples of ancient Egyptian mathematics.

It is named after Alexander Henry Rhind, a Scottish antiquarian, who purchased the papyrus in 1858 in Luxor, Egypt.

It was apparently found during illegal excavations in or near the Ramesseum. It dates to around 1550 BC.

Extreme angle shooting, something many shooters never account for, but it is a skill that should be worked. I have known many a hunter that will take a cross canyon shot over an extreme angle shot because they can't figure the angle and would rather keep the baseline shot simple. They have relied so long on that flat earth shot that they miss the big one that is down hill 20 degrees. I'm talking about pythagoras theorem.

The shooter can be either at the top of "A" or at the long end of "B", if they shoot with out knowing the answer to "C" and they range for a "flat earth" shot each bullet will strike high. In both cases the shooter had ranged for "C" (The distance for "C" will be longer than the distance for "B".) causing the bullet to strike high, what they needed was to range for "B", the actual range and not the perceived range of "C". Follow me for more Army shit I still remember after all these years.

A History of Mathematics | October

We have decided to share more interesting facts from the history of mathematics. We have been doing this for two months (August and September) and it was a great way to find out more about some great mathematicians, but also remind ourselves about some great mathematical concepts. We are continuing with the same idea in October. Hope you will like these posts!

Saw this somewhere on the internet showing an interesting take on Pythagoras theorem. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. Sorry can’t remember source.

NCERT Rewrites Geometry’s History With Baudhāyana at the Center

For most students, the formula a² + b² = c² is learned early and remembered for life. It is almost always introduced as the Pythagoras theorem, named after the Greek philosopher Pythagoras. From school classrooms to competitive exams, generations have grown up believing that this fundamental idea of geometry originated in ancient Greece. However, a recent change in India’s school curriculum is prompting students to look at this familiar equation from a very different historical perspective.
