How do you pronounce Huygens?

Cassini Huygens is a spacecraft designed to orbit Saturn. You would think to pronounce it Cassini Hugyens but it is wrong. Its pronounced (Cassini Hoy-gens) named after Titans discoverer. You don't want to look stupid and pronounce it (cassini hUygens) trust me I would know.

Who is the mathematician invented the real numbers?

Egyptians created the first chipered numeral system around 3,400 BC. Then followed by the Greeks by mapping their counting numbers onto Ionian and Doric alphabets. Well numbers mean many things: counting, or spoken values, or written values and lastly structured standardized written numbering.

Ancient man has been counting since before they could walk upright. This has been shown by apes who will sometimes orgainize in a linear order...which is basically crude counting. One, two, three bannanas.

Ancient pre-Sumerian civilizations as far back as 8000BC used a numeration that was basically fingernail marks on clay.

Sumerian civilization had "standardized" their numbering system by about 3000BC. Which had a structured 1-6 counting. A circle with lines inside, kind of like cutting out pie pieces.

It can be said that the first WRITTEN numbers were done by the Ancient Egyptians found in hieroglyphs about 2700 BC.

They had symbols for 1, 10, 100, 1000, 10000, 100000 and 1000000.

Egyptians later revised the symbols using lines that included unique symbols for 1 thru 10 at about 2200 BC.

The ancient Indian cultures also evolved multiple number sets Brahmi, Gupta and Nagari number sets as early as 3000BC. But there was so much variance on the numbering between areas the "dates and origins" are still debated today.

Cultures created all kinds of numbering systems Greeks, Romans, Persians, and Arab/Islam.

The idea to create individual symbols for each number between 1 and 9 sprouted in many cultures as far away as China and Mayan cultures. Indian culture proposed a standardized set in about 800AD which is used by India and some nearby nations.

What we call the European numbers were evolved in the Iberian peninsula during the Moors/Christian battles 400 to 1400 AD, what is know as modern day Spain and Portugal. During the battles the Christians learned from what the Moors had collected over their empire. So Symbols for Numbers 1 2 3 4 5 6 7 8 9 0 were standardized by about 1400 AD spread with Latin/Christian based cultures.

To this day...there are still many cultures who use their own numbering system.

Consider and indoor ski resort. The longest ski run drops 51 ft and has an angle of depression of approximately 6.7 degrees Find the length of the ski run.?

The alternate angle of depression is the angle of elevation and so 51/tan(6.7) = 434 ft which will be the length of the ski run providing the given information forms a right angle triangle.

Were was the death of Aristotle?

What is Leonhard Euler contribution in mathematics?

Among other mathematical activities, Euler introduced certain mathematical notation for use by mathematicians such as the symbols e and i, made contributions in differential equations, developed the foundations of mathematical analysis, showed that e was an irrational number, proved one aspect of Fermat's Last Theorem, disproved Fermat's conjecture about "Fermat primes" by factoring the fifth Fermat number, computed Reimann zeta functions, and made contributions to the three-body problem. He also made contributions to fields in physics, such as electricity and magnetism.

he was the best mathematician of all time!

How old is Blaise Matuidi?

How does a boat have buoyancy?

It's hard to describe. The easiest way to say it, is that the weight is offset. Archimedes' principle sates that any FLOATING object displaces its own weight of fluid.

Why is the hippocratic oath considered a medical advance?

The hippocratic oath is a medical advance because it forces doctors to pledge not to do harm to their patients.

What did Aristotle have to do with pi?

He was the first one to calculate the value of pi

* * * * *

Actually, Aristotle did not have much to do with pi. It was Archimedes who was the first to make a serious attempt to find the value of pi by calculating the perimeters of incribed and exscribed polygons with increasng number of sides.

I guess the Communiy got an ancient Greek philisopher whose name began with A. Well done!

What did Aristotle say?

He said "we are what we repeatedly do, excellence then is not an act, but a habit."

What is the pattern for Fibonacci sequence?

Two consecutive numbers are added together to get the next one.

1,1,2,3,5,8,13...

What is Archimedes pricipal?

an object is immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object...

i know alot

tee hee

What did Archimedes use magnets for?

Archimedes is purported to have used loadstones to remove nails from enemy ships thus sinking them.

What do we use the pi symbol to represent a number?

Because pi is an irrational number that has an infinite amount of digits
