On September 6, Beijing time, in order to further understand the earth inhabited by humans and the vast and complex universe, scientists have developed a series of ambitious new tools. With the help of these expensive large scientific instruments, they discovered many secrets of the earth and the universe. Developing large-scale scientific instruments is not easy. Sometimes it takes decades of efforts from multiple countries, and the investment is even more astronomical. With the help of these awesome instruments and equipment, scientists continue to deepen their understanding of the earth and the universe. The implementation of large-scale scientific projects is extremely difficult. Four objective factors must be considered, namely the development cost, operating cost, number of personnel, and the huge scale of the equipment. In addition, we have to consider three subjective factors, namely the use in scientific research, the use to the general public (what can be done for us) and the so-called "wow factor". 1. "Earth Exploration" Project "Earth Exploration" Project The "Earth Exploration" project is the world's largest scientific project for tracking the geological evolution of North America. The observatory recorded data with an area of ​​more than 3.8 million square miles (about 9.84 million square kilometers), with a data volume of 67TB (terabytes). In addition to the analysis of the sliding of the San Andreas fault, the "Earth Exploration" project is also responsible for analyzing the magma columns underground in Yellowstone National Park. 2. Large Hadron Collider Large Hadron Collider The Large Hadron Collider is the world's largest particle collider, with an annual operating cost of about 1 billion US dollars. The people involved in this project come from 60 countries and the number of people exceeds 10,000. This collider aims to uncover the most basic secrets of cosmic physics. One of the major tasks is to find the Higgs meson called "God Particle". 3. Divergent neutron source Scattered neutron source The diffuse neutron source is a powerful movie camera used to photograph molecules. It is equipped with a particle accelerator, which emits pulses to a target chamber (each pulse contains 2000 trillion neutrons), and reflects after touching the material in the target chamber. The scattered neutron source does not create an explosion, and is more suitable for researching how to develop higher performance batteries and other devices. 4. International Space Station International Space Station The annual operating cost of the International Space Station is as high as 2 billion US dollars. It is the longest man-made facility in space. The number of personnel involved in this project has reached thousands. As of November 2011, the space station has been in space for 11 years. This orbital laboratory is used to carry out various experiments and has helped scientists develop a salmonella vaccine. 5. Advanced light source particle accelerator Advanced light source particle accelerator The advanced light source particle accelerator is located in Berkeley, California, USA, and can introduce photons with a brightness of 1 million times of the surface of the sun into proteins, electrodes, superconductors and other materials to reveal their atomic, molecular and electronic properties. Scientists used this accelerator to create a 3D image of ribonucleic acid polymerase and the dust describing the comet tail. 6. "Juno" Jupiter Probe "Juno" Jupiter Probe The "Junuo" probe will enter Jupiter's orbit in 2016. Before that, it will travel toward Jupiter at a speed of 134,000 miles per hour (about 215,000 kilometers per hour). Juno is one of the fastest spacecraft in human history. It will orbit Jupiter for 33 weeks, then crash into Jupiter, burning like a meteor in Jupiter ’s hydrogen atmosphere. 7. US National Ignition Device US National Ignition Device The US National Ignition Device is located in Livermore, California. It is the world ’s largest and most powerful laser, with a length equivalent to 3 football fields and a height of 10 floors, generating 2 million joules of ultraviolet energy. The national ignition device can reach temperatures and pressures similar to the star's core. 8. Very large telescope array Very Large Telescope Array The Very Large Telescope Array is one of the largest telescopes in the world, consisting of 27 individual radio antennas, each with a diameter of 82 feet (about 25 meters). Very large telescopes can take detailed images of near-Earth objects such as the moon or astronomical objects as far as the observable edge of the universe. 9. "Neptune" Observatory "Neptune" Observatory The "Neptune" Observatory is the world's largest submarine observatory, consisting of approximately 500 miles (approximately 804 kilometers) of cables and 130 instruments equipped with 400 sensors, which can continuously monitor the marine system on a large scale. For the first time. The monitoring objects of the "Neptune" Observatory include the life, geology and chemical characteristics of marine animals. 10. Relativistic heavy ion collider Relativistic heavy ion collider The relativistic heavy ion collider is located on Long Island, New York. The collision of gold ions produces a temperature of 7.2 trillion degrees Fahrenheit. Such high temperatures can melt protons and neutrons. With the help of the relativistic heavy ion collider, scientists are able to reconstruct the cosmic environment one millionth of a second after the Big Bang
Manufacturer of skating roller shoes such
as Roller Skate, inline Skating Shoes and Ice Skate.
Skating shoes factory at the high quality,
competitive prices and the right time to strive to maintain our extensive
cooperative relationships with you.
OEM or ODM is available. Welcome to contact
us.
Any good skater would have gone through
multiple different set-ups. It can take me a while to get used to a new boot,
plate, truck or wheel so be sure to be patient with your adjustment period. We
all have individual needs. Your set-ups should be customized to suit the
personal style of the skater. Most skaters own more than one pair of skates,
plates and trucks and many pairs of wheels, bushings, bearings and other
interchangeable parts. It is important to experiment and figure out what works
best for you individually.
Ice skating is a sport in which people
slide over a smooth ice surface on steel-bladed skates. Millions of people
skate in those parts of the world where the winters are cold enough. Although
most people ice-skate for recreation and exercise, skating for form and speed
is a highly competitive international sport. Ice-skating skills are also an
important part of the game of ice hockey. Ice-skating shows, such as the Ice
Follies and the Ice Capades, have entertained millions of spectators. These
shows also provide a means for skaters to exploit their talents commercially.
The increasing number of indoor rinks has made year-round ice skating possible.
Inline Speed Skates come with
3 or 4 wheels. The shoes are close-fitting and have little padding. Most call
this sport Inline Racing. Many people who are inline racing switch back and
forth between this and ice speedskating. My guess is that the shoes and frames
for ice speed skating and inline racing are built similarly, making it an easy
transition.
Skating shoes styles are
roller skates shoes, inline skates shoes and ice skates shoes for kids, men and
women.
