Mathematicians

Often, to completely understand the importance of a mathematical theory, it's essential to know about the person who developed it. This category is where all questions about historically significant mathematicians should be asked.

What did Copernicus do for a living?

Nicolaus Copernicus was , by trade, a mathematician and astronomer. With this background, he was well suited to establish his theory of heliocentrism.

What did Zhang Heng invent?

Chinese inventor Zhang Heng is credited with several inventions. The world's first seismometer is one of his inventions. Zhang Heng also invented the water-powered armillary sphere.

What is heron's formula?

If A is the area of a triangle with side length a, b and c and s is (a+b+c)/2 ( known as the semiperimeter of the triangle) Then, Heron's formula tells us that A=square root of [s(s-a)(s-b)(s-c)].

Where did nicolaus Copernicus die?

Nicolaus Copernicus died in what is now Frombork, Poland, on May 24, 1543. Copernicus is the father of modern day astronomy.

What is Pythagoras' theorem?

Pythagoras' Theorem is a statement proving that in a right angled triangle the square of the longest side (the hypotenuse) equals the sum of the squares on the other two sides.

The formula for this is: A squared + B squared = C squared. C represents the hypotenuse on this formula, while A and B represent the other two perpendicular sides.

Exercise:Use squared paper & draw a triangle in the center of the page. Make the short sides of length 6 cm & 8 cm. Draw a square on each side. Measure the area of each square: hint 6 x 6 = 36 and so on. Having found the areas, add the areas of the squares on the two shorter sides. Compare your answer with the area of the square on the longest side. What do you notice? Repeat this for more triangles and see if you can see a pattern.

(The use of upper case for vertices and lower case for the actual sides of a triangle is prevalent. So we write triangle ABC having sides of length a, b, c.)

Did Archimedes jump out of the bath and shout eureka?

yes he did, and he also run into the streets of siracuse naked shouting this

Is there Geometry in hockey?

Different types of mathematics can be applied to hockey. To answer your question, trigonometry, for example, can be used to measure the angle at which the puck must leave a player's stick (in any area of the ice) in order to pass through one of the goalie's holes and into the net.

What is the Riemann hypothesis?

The Riemann Hypothesis was a conjecture(a "guess") made by Bernhard Riemann in his groundbreaking 1859 paper on Number Theory. The conjecture has remained unproven even today. It states the "The real part of the non trivial zeros of the Riemann Zeta function is 1/2"

What are the eleven problem solving strategies or tools by george polya?

drawing a diagram drawing a table acting out guess and check creating an prganized list looking for a pattern creating a tree diagram working backwards open ended problem analyzing and investigating using logical reasons

Who is Nicholas Copernicus and what is his contributions?

Nicolas Copernicus (1473-1543) is said to be the founder of modern astronomy

He is famous for his theory which asserted that the earth rotated on its axis once daily and traveled around the sun once yearly:

How did Archimedes discover pi?

Archimedes found a method for finding good approximations to the ration of the circumference of a circle to the diameter. He did this by inscribing polygons inside the circle and finding how the perimeter changes when the number of sides is doubled.

Archimedes came up with an approximation that is equivalent to saying that pi is between 3 1/7 and 3 10/71. This is quite far from being as accurate as what you showed.

Copernicus believed that?

the sun is the center of the solar system.

What did Nicolaus Copernicus invent?

Nicolas Copernicus developed the model of the solar system that says that the sun is the center of the universe and that all of the other planets are orbiting it.

How did Pierre de Fermat die?

After gorging himself on his oh so favourite meal of Wigets (Small Marinated Midgets) Fermat unfortunately put on those few crucial stone that tipped his weight over the limit. His cheeks grew that bit too large and whilst sleeping in his bed he choked on his own cheeks, though some say he was deliberately trying to eat them...

Who is Zhang Heng?

Zhang Heng was a famous astronomer and mathematician. He was also an inventor. He had some great invention that helped human. One of his most famous works is the thing that can detect earthquakes.

Name 6 mathematical contributions of Leonhard Euler?

Euler introduced mathematical notation. He made contributions of complex analysis. He introduced the concept of a function, the use of exponential function, and logarithms in analytic proofs. Euler also produced the formula for the Riemann zeta function.

How did Carl Friedrich Gauss die?

Carl Friedrich Gauss died in his sleep on February 23, 1855 after years of deteriorating health in Hannover. It was in the early morning. He was buried in the cemetery Albanifriedhof but his brain was preserved.
