How to become good in studies?

I try to study 2 hours daily,

One thing I do is a make flash cards. I have them up into a puzzle. I make the meaning in one, and the other half the question to the meaning,.

I put them into a brown bag and shake me up. Than I get them out and try to match the question with the answer.

I try different things with the same subject. I record my question and than answer it. While I am getting dress. and hear the type that I recorded.

But at time I am not consistence in the time I study daily. Does any one have new ideas for me.

Why Laplace transform not Laplace equation?

Laplace equation:

in 3D U_xx+U_yy+U_zz=0

Or in 2D U_xx+U_yy=0 where U is a function of the spatial variables x,y,z in 3D and x,y in 2D.Also, U_xx is the second order partial derivative of u with respect to x, same for y and z.

Laplace transform:

L(f(t))=integral of (e^(-s*t))*f(t) dt as t goes from 0 to infinity. Laplace transform is more like an operator rather than an equation.

Did blaise pascal believe in god?

yes he did believe in god, have you heard of pascals wager? it states that: žPascal believed that: believing in god is just a gamble. He believed that you either live in this world as if there is a god, or you live in this world as if there is not a god.

Yes. I think? because he make a adding machine? i think why he make the adding machine cause he want to make math easier to other people. hehehehehe!!! stupid answer!

What was leonhard euler known for?

Euler contributed to the subjects of geometry, calculus, trigonometry, and number theory. He standardized modern mathematical notation using Greek symbols that continue to be used today. He also contributed to the fields of astronomy, mechanics, optics, and acoustics, and made a major contribution to theoretical aerodynamics. He derived the continuity equation and the equations for the motion of an inviscid, incompressible fluid.

Who is the first woman mathematician?

Hypatia of Alexandria (355 or 370 - 415) - Greek - philosopher, astronomer, mathematician - She was the salaried head of the Neoplatonic School in Alexandria, Egypt, from the year 400. Her students were pagan and Christian young men from around the empire.

What scientific belief did Francis Bacon and René Descartes share?

That Nature could be explained through abstract reasoning and experimentation.
The scientific belief that Francis Bacon and Rene Descartes shared was their belief that most of the knowledge that came before was weak, sloppy, and in some cases very wrong. They both believed knowledge should be received by personal observation.

What is the best production of King Lear?

I assume you are not asking which was the best stage production, since stage productions are ephemeral, and even if they were great, you cannot go back and revisit them. So let's talk about recorded performances.

My personal favourite stars Ian Holm and was produced by the Royal National Theatre company and filmed by BBC in 1998, reissued in the Americas by WGBH Boston in 2004. The settings and costumes are very simple and do not distract from the truly wonderful acting all around.

But if you don't like your Shakespeare straight up, you might consider Sir Laurence Olivier's version recorded for television in 1984, which has a bit more realistic set and has some great performances from a first-rate cast. Some people think Olivier was past it at this point in his career; I have the opposite viewpoint.

Considered by many the classic version of King Lear is Peter Brook's production starring Paul Scofield. Made in 1970 in black-and-white, it portrays an iron-age society in a grim, bare, rocky, snow-covered landscape. Lear and those around him are tough, brutal and unfeeling. This play is as much about Lear discovering that he has feeling as anything else. (But then, isn't the play about him discovering his humanity?)

Another influencial version made at about the same time and also in black-and-white is in Russian, directed by Grigori Kozintsev. It stars Estonian sctor Juri Jarvet in the title role. There is also a feeling of desolation as in the Brook production, but this one brings out more of the social relationship of a king to his people, and of the commonality of all people no matter what their social status, surely a very important theme in the play.

Watch these four versions and decide for yourself.

As for other recorded versions, those starring Ian McKellen, James Earl Jones and a silent version by Frederick Warde are adequate and have moments of interest. I wouldn't bother with those starring Orson Welles, Patrick Magee, Michael Hordern or Brian Blessed.

Who was Fibonacci?

Leonardo Pisano Fibonacci, or Leonardo of Pisa, was a famous mathematician, who introduced the modern numeric system that many nations use nowadays, born and raised in Italy. Alongside introducing numbers, he developed the now famous Fibonacci Sequence, which adds together the two previous numbers in the sequence; 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, etc.

What is the rule to the Fibonacci sequence?

The rule for the sequence is an = xn-1 + xn-2

The sequence of numbers, 1, 1, 2, 3, 5, 8, 13, . . . , in which each successive number is equal to the sum of the two preceding numbers.

How rich was nicolaus Copernicus?

Nicolaus Copernicus was a wealthy man as he came from a family of merchants in Poland. However, his wealth was not on the level of the nobility or great aristocrats of his time. He was financially comfortable due to his inheritance and income from his work as a church canon and administrator.

How fat was nicolaus Copernicus?

There is no definitive information on Nicolaus Copernicus's exact weight or body composition as historical records do not provide this detail. Copernicus is known for his contributions to astronomy, particularly for proposing a heliocentric model of the solar system.
