Time goes by so quickly, in a blink of an eye again to the age not, the new year will be kicked off, in this farewell, day and night with our calendar should be changed, shopping malls in the sale of the calendar, although it is exquisite, but not personalized, and expensive, with the Word 2010 Calendar Wizard to create a unique New year calendar, economic benefits , but also to show their personality style. 　　First, create a New Year calendar Although the calendar looks very simple, but becau

expect so much. The distance from the Earth to the moon is about 384,000 kilometers, short in the entire cosmic scene, but it can already plug all the planets in the solar system. If we compare the Olympus Mountains on Mars to the mountains of the earth ... The earth is the pediatrics ah ... Olympus is 27 kilometers high, almost 3 times times the height of Mount Everest, and more than twice times higher than the Maunaki volcano (calculated f

This is a practical php date-time operation class, which includes the Gregorian-lunar conversion, converted to Chinese date format, the calculation of the lunar calendar days apart, the lunar calendar year to obtain the lunar calendar days, the number of days to obtain the lunar calendar year, get a leap month, calculate the lunar date and the first day of the first month, calculate 2 Gregorian calendar ( Solar calendar) The number of days between dat

of the data, finally with the theory of conic section (Greece has) to fit successfully.In 1609, taking Mars as an example, the second law of Kepler , the uniform law of Plane velocity, was published.The First Law is that the orbits of planetary motion are elliptical.In 1619, the third law of Kepler , also known as the Law of reconciliation, was put forward, and in the harmony of the universe, the square of each planet's revolution was proportional to the cubic of the ellipse's orbital half-leng

around the planet. In computer science, an interval of 10 milliseconds is called a jiffy.One-tenth secondsIn the parable, the "Blink of an hour" is one-tenth seconds. The human ear takes a second to discern the sound echo. Flight number 1th, flying away from the solar system, flies about two km from the sun every one-tenth seconds. The Bee Sparrow can beat 7 wings in this time. The tuning fork for A to medium C is vibrating 4 times.One secondThe hear

this year 4 Month - Mars "Curiosity" turned on the mast camera aimed at Ceres ( Ceres ) direction. The journey to Ceres on the Martian cold night sky, Dawn the Deep Space spacecraft "Dawn". Thus, Curiosity has not died yet. -"Dawn" (Dawn)Deep Space Spacecraft (spacecraft) Take off. Where is it going to fly? "Dawn" wants to examine two asteroids:Vest(female focal star) andCeres(Ceres). The focal star and Ceres are very large asteroids, very far away from the sun. are in two astronomical units (A

1904 Russian scientist Jukovsky ( Nikolai zhukovsky1847-1921 A modern wing theory was created to illustrate the reason for the wing to generate lift in flight and to give a rigorous proof in mathematics. Since then, people have a scientific concept of the wing. Scientists are not businessmen who have created The great achievements of humanity in the past century. say the truth, Sunshine Power 2 The solar plane is actually a pair of artificial "big wi

, therefore, it can be considered that the coordinates are represented in the cts of any earth-solid reference system. 16. Calculate the time when a GPS signal is sent from a satellite (minus the delay of the receiver transmission time) GPS observations are the functions of satellite and receiver oscillator frequencies and propagation time latencies. propagation time latencies include geometric propagation time latencies and atmospheric propagation time latencies, namely: 2.2.15 The parameters

I saw a black hole on TV last night. There are hundreds of black holes in the galaxy, and there is a giant black hole in the center of the galaxy (10 million times the weight of the Sun). If we were captured by them, the entire solar system will be completely torn apart by it. This assumption is not completely impossible, and the program also simulates the situation where the solar system is captured and to

provides some columns of programmable modules and kits. Its platform and hardware are both open-source, but its products can be used to develop commercial products with closed source. The company also provides its own development Leasing Service. 12. pinoccio The Arduino-compatible pinnoccio Development Board (known as the "Boy Scouts") is interconnected into a low-power mesh network. They include a built-in rechargeable battery that can be connected to so
