Babylonian mathematics refers to any mathematics of the peoples of Mesopotamia modern Iraq from the days of the early Sumerians through the Hellenistic period almost to the dawn of Christianity. The first few hundred years of the second millennium BC Old Babylonian period , and the last few centuries of the first millennium BC Seleucid period. Later under the Arab Empire , Mesopotamia, especially Baghdad , once again became an important center of study for Islamic mathematics. In contrast to the sparsity of sources in Egyptian mathematics , our knowledge of Babylonian mathematics is derived from more than clay tablets unearthed since the s. Some of these appear to be graded homework. They developed a complex system of metrology from BC. From around BC onwards, the Sumerians wrote multiplication tables on clay tablets and dealt with geometrical exercises and division problems. The earliest traces of the Babylonian numerals also date back to this period.

The physics is discussed in two subsections: Descartes apparently received the stimulus to study these works from Isaac Beeckman ; his earliest recorded thoughts on mathematics are found in the correspondence with Beeckman that followed their meeting in As Descartes wrote in his Rules for the Direction of the Mind ca.

It uses concepts such as abstraction and logic, numbering and calculation, measurement of volume and distance, and the quantification of shape and motion (which includes speed) (1).

For my Algebra 2 students, I gave them a list of exponent rules. We wrote a word summary of what type of problem each exponent rule would help us with. My marker choice was not good for photographing They were really struggling with applying these to the problems we were simplifying. They kept claiming that they just didn’t know where to start. Eventually, I broke down and gave them an order of steps to follow.

This helped them a lot. Though, I wish they could solve these problems without me writing out step by step directions. We were working on simplifying expressions like this: We don’t have time to derive all of the rules from scratch. But, they act like they’ve never seen anything like this before.

Cuckold fetishists, dominatrix customers, scat sex users, and so many of these other fetishes are almost wholly separate from the act of fucking very often, they forbid it. Being whipped by a leather-clad hooker or stroking it for hours to Jewish-produced porn is totally different from fucking. Porn is not sex, nor are all the fetishes associated with sex. Sex drive and wanting to fuck women is healthy.

PJ London May 10, at 8: Gravitational lensing exists as a function of the force of gravity. Time as a perceived continuum exists both forward and backward. What properties excluding distance, a perceived continuum and gravity exist to prove spacetime? In other words, what properties does spacetime have that are not properties of some other function. Total circular logic, as I pointed out, happiness exists, so why should light not be propagated through happiness?

It requires a molecular, atomic or nuclear transition of energy to release a photon. If you have information to the contrary, please advise.

Posted on June 20, by The Mathematician Mathematician: It is not uncommon to hear physicists or mathematicians talk about the beauty, simplicity or elegance of equations or theorems, and even claim that they are sometimes led to a correct formula or away from an incorrect one by considering what is simple or elegant. Consider, for example, the words of the Nobel prize-winning physicist Murray Gell-Mann: It was beautiful and so we dared to publish it, believing that all those experiments must be wrong.

In fact, they were all wrong. Is elegance in mathematics evidence for an underlying structure to reality? Or can this be explained away by psychological or practical considerations? To begin answering these questions, an important thing to notice about the aesthetics of equations is that what appears to be simple or elegant may sometimes only be so because of the way that symbols are defined.

Is it not astounding that we can describe such a powerful physical law with just 5 symbols? A deeper look at this equation shows us that the apparent simplicity here is in part an illusion. First of all , which is known in this context as the Laplace operator, can be thought of as simply a short hand notation.

Eat one of those and your tummy will curl right up! Seriously speaking, a favorite attack on radiometric dating involves dangling “horror stories” about gross errors before the reader, thus giving the impression that radiometric dating is totally unreliable. Woodmorappe , with his collection of some bad radiometric dates, must surely be the master of that technique. Upon being presented with claims that radiometric dating is totally erroneous, a question naturally arises: If radiometric geochronology is half as bad as Woodmorappe’s list suggests, then how in the world did geologists ever arrive at a tight consensus for the official dates?

Look at the various radiometric tables in use over the last 20 years or so and you will find, at least for the fossil-bearing strata, a remarkably tight agreement.

Play media By placing a metal bar in a container with water on a scale, the bar displaces as much water as its own volume , increasing its mass and weighing down the scale. The most widely known anecdote about Archimedes tells of how he invented a method for determining the volume of an object with an irregular shape. According to Vitruvius , a votive crown for a temple had been made for King Hiero II of Syracuse , who had supplied the pure gold to be used, and Archimedes was asked to determine whether some silver had been substituted by the dishonest goldsmith.

While taking a bath, he noticed that the level of the water in the tub rose as he got in, and realized that this effect could be used to determine the volume of the crown. For practical purposes water is incompressible, [19] so the submerged crown would displace an amount of water equal to its own volume. By dividing the mass of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added.

Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress, crying ” Eureka! Moreover, the practicality of the method it describes has been called into question, due to the extreme accuracy with which one would have to measure the water displacement. This principle states that a body immersed in a fluid experiences a buoyant force equal to the weight of the fluid it displaces. The difference in density between the two samples would cause the scale to tip accordingly.

Galileo considered it “probable that this method is the same that Archimedes followed, since, besides being very accurate, it is based on demonstrations found by Archimedes himself. Archimedes’ screw The Archimedes’ screw can raise water efficiently.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved. You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular.

Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.

Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations. They did not have the benefit of cheap, off the shelf, mass produced batteries. For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item.

Expanded equation of a circle Video transcript – [Voiceover] So we have a circle here and they specified some points for us. This little orangeish, or, I guess, maroonish-red point right over here is the center of the circle, and then this blue point is a point that happens to sit on the circle. And so with that information, I want you to pause the video and see if you can figure out the equation for this circle.

This step paves the way for the general solution of the cubic and quartic equations (material dating back to Descartes’s earliest studies)and leads to a general discussion of the solution of equations, in which the first method outlined is that of testing the various factors of the constant term, and then other means, including approximate.

Science and Its Times: Bibliography of Primary Sources Apollonius of Perga. This work consisted of 8 books with some theorems. In this great treatise, he set forth a new method for subdividing a cone to produce circles, and discussed ellipses, parabolas, and hyperbolas—shapes he was the first to identify and name. In place of the concentric spheres used by Eudoxus, Apollonius presented epicircles, epicycles, and eccentrics, concepts that later influenced Ptolemy’s cosmology.

Even more significant was his departure from the Pythagorean tendency to avoid infinites and infinitesimals: The most important factor in this monumental work, however, was not any one problem, but Apollonius’s overall approach, which opened mathematicians’ minds to the idea of deriving conic sections by approaching the cone from a variety of angles. By applying the latus transversum and latus erectum, lines perpendicular and intersecting, Apollonius prefigured the coordinate system later applied in analytic geometry.

On the Equilibrium of Planes c. Here Archimedes considered the mechanics of levers and the importance of the center of gravity in balancing equal weights. On the Sphere and Cylinder c. In this work Archimedes built on the previous work of Euclid to reach conclusions about spheres, cones, and cylinders. As described in The Scientific Simmons
