At infinitesimal thickness the discrepancy between the inner and outer surface area of any given shell is infinitesimal, and the elemental volume at radius r is simply the product of the surface area at radius r and the infinitesimal thickness.

It is an ending point an infinitesimal boundary to the universe.

The system of hyperreal numbers is a way of treating infinite and infinitesimal quantities.

He made important discoveries in fields as diverse as infinitesimal calculus and graph theory.

And when I realize the infinitesimal part of this I possess, it makes me shudder.

Consumers would find it incomprehensible that even an infinitesimal quantity of prohibited GMOs could be tolerated.

This approach fell out of favor in the 19th century because it was difficult to make the notion of an infinitesimal precise.

In 1925 Peano switched Chairs unofficially from Infinitesimal Calculus to Complementary Mathematics, a field which better suited his current style of mathematics.

In number systems incorporating infinitesimals, the reciprocal of an infinitesimal is an infinite number, i.e., a number greater than any real number see 1 .

The principle of this exceptional practice is quite scandalous. Until now, poisoning has been legal provided that it is carried out in infinitesimal doses.

But we'll always have an infinitesimal amount of carbon. But let me ask you a question. Let's say I'm just staring at one carbon atom.

The elements that make up the ceiling grid and the lighting, they're all losing their modular quality, and moving more and more to these infinitesimal dimensions.

An infinitesimal number could be greater than 0, but less than any number in the sequence 1, 1 2, 1 3, ... and less than any positive real number.

Thus, the derivative of f(x) becomes formula_4 for an infinitesimal formula_5, where st( ) denotes the standard part function, which rounds off each finite hyperreal to the nearest real.

However, the concept was revived in the 20th century with the introduction of non standard analysis and smooth infinitesimal analysis, which provided solid foundations for the manipulation of infinitesimals.

We learned in that very first video that the nucleus is almost an infinitesimal portion of the volume of this sphere where the electron will be 90 of the time.

The hyperreals, or nonstandard reals, R, are an extension of the real numbers R that contains numbers greater than anything of the form formula_1Such a number is infinite, and its reciprocal is infinitesimal.

Physical intuition Intuitively, the theorem simply states that the sum of infinitesimal changes in a quantity over time (or over some other variable) adds up to the net change in the quantity.

Analysis The development of infinitesimal calculus was at the forefront of 18th Century mathematical research, and the Bernoullis family friends of Euler were responsible for much of the early progress in the field.

Contributions to mathematics and physics Euler worked in almost all areas of mathematics, such as geometry, infinitesimal calculus, trigonometry, algebra, and number theory, as well as continuum physics, lunar theory and other areas of physics.

formula_11 is an infinitesimal line element (or differential 1 form) along the curve C , that is, a vector with magnitude equal to the length element of C , and direction given by the tangent to the curve C ).

Because of this, the Principia has been called a book dense with the theory and application of the infinitesimal calculus in modern times and lequel est presque tout de ce calcul ('nearly all of it is of this calculus') in Newton's time.

But I just want to repeat that because that little infinitesimal spot that we talked about before, where even though it's a very small part of the fraction of the volume of an atom it's actually almost all of its mass that's what I'm zooming out to this point here.

The standard definition of the number 0.999... is the limit of the sequence 0.9, 0.99, 0.999, ... A different definition involves what Terry Tao refers to as ultralimit , i.e., the equivalence class (0.9, 0.99, 0.999, ...) of this sequence in the ultrapower construction, which is a number that falls short of 1 by an infinitesimal amount.
