Looking back suddenly, looking at the end of the world, who will be poetic and poetic throughout the years, quietly write to describe a romance, in this life, how to let the charm of the wind and moon make each other know? I feel pity, I don't feel sorry for the fragrance and jade, I look forward to a flower blooming, fragrant dyeing the whole spring, and a beautiful time; I am still pitiful, not sad that the wind is swept by the butterflies, looking forward to a thick shade, soaked in the quietness of a party, and a good relationship; I am humble and merciful, not sad that the mountains and rivers will be silent forever, looking forward to a curtain of smoke and rain, contaminated with a blur, and a story gracefully.
Once upon a time, sighs flowed slowly through the cracks of time like water, and I don't know whose other side it flowed to? I never dared to hope that an unexpected encounter would be able to stay together until old age and be free for a lifetime. Walking in the long world, I am probably tired of being full of elegance.
I always want to learn ginseng Zen, and I longs for a Sanskrit sound to hit my ears, so I sit cross-legged in front of the Buddha, turn a string of Buddhist beads and quietly erase the long-buried obsession in my heart. Then leaned quietly on the lintel, silently, wanting to let go of the time, not thinking about the past, not cutting off the old dreams and long-cherished wishes, with a Bodhi heart shallow and peaceful, quietly enjoy all things in the world.

The inventors of logarithms in the annals of mathematics are two people: John Nepple of England and Joebster Boulki of Switzerland.
Originally a watchmaker, in 1603 he was appointed as a court technician in Prague, and he came into contact with the famous astronomer Kepler and learned some details about astronomical calculations. He observed the hard work of astronomers and decided to provide them with easy calculations.
The simple calculation method provided by Bourkey is a practical logarithmic table. In principle, Stephen has solved the problem of converting multiplication (division) to addition (subtraction). However, the numbers in the two sequences given by Stephen are too limited to be practical, and a practical logarithmic table must include all the numbers to be multiplied.
In order to do this, Bourki took the approach of listing the proportional series as closely as possible. The proportional series he gives and its corresponding equal difference series are equivalent to:
Here, 1 in the equal difference series corresponds to (. That is to say, when Burke made the table, he took the base of the logarithm as, which is not far from the base e= of the natural logarithm. But what needs to be pointed out is that neither Bourki nor Neppel, which will be discussed later, have any notion of a logarithmic "bottom". Because none of them define the logarithm x=logan from the relation of ax=n.
Born in Edinburgh, Scotland, Nepoel was a Scottish nobleman who entered the University of St Andrews' Sparchgyll College at the age of 12. At the age of 16, before graduating from university, he traveled and studied on the European continent, enriching his knowledge. Naiper was not a professional mathematician, but he loved mathematics and worked hard in an era that required a revolution in computing technology.
As he says, "I always try not to get my energy and talents out of the troublesome and monotonous calculations that are often daunting to the learner." During his lifetime, he spent 20 years perfecting the "Neppel analogy" in the spherical triangle, the "Neppel Circle Rule" and the "Neppel Arithmetic" for multiplication and division.
In 1614, Neppel published his Notes on the Wonderful Logarithmic Table, in which he not only proposed the first logarithmic table in the history of mathematics (Bourki's logarithmic table was published in 1620), but also described the thought process of the invention.

The water cooling of the second ** is good, and the heat dissipation effect is good.
-
The first Joebers is better, look at the material, the first one is pure copper thermal conduction, and the Patriot is aluminum sheet thermal conduction, that is, the brand is good, and the low-end goods are really not good! The downstairs will only look at the signs, I don't understand!
-
Patriot, after all, brand products, guaranteed.
-
It's pretty much the same, just choose which one you like.

Hello, the engine of this 04 Mazda6 is an imported engine, and the quality is good.

The first mathematician to use log should be Euler, including the natural constant e, which was also the first to be used by Euler.
