One of many world's specialists on hammerhead sharks, marine biologist Pete Klimley is scuffling with the stereotype of sharks as primitive and harsh killers. in reality, hammerheads convey a few remarkably refined social behaviors, together with their education within the hundreds and hundreds at underwater seamounts within the Pacific Ocean. to inform the tale of those fabulous animals, writer Ken Mallory talked with Pete Klimley after which traveled to tiny Cocos Island, 330 miles off the Pacific coast of Costa Rica. There, he had the opportunity of an entire life to work out those awe-inspiring animals up shut.

Example text

2) Beta particles (␤) are electrons with a lot of energy. They come from the breakup of a neutron in the nucleus of the unstable atom into a proton and an electron. Beta particles are used to treat and kill cancer cells, and in PET brain scanners. hAlpha radiation is easily stopped by thin materials, like paper or skin. Beta radiation is stopped by less than an inch of metal. Gamma radiation is hard to stop even with a thick piece of lead! 3) Gamma (␥) and X-ray radiation are made of photons with very high frequency and energy.

These particles were called kaons. 50 In the 1950s, new technology in particle physics brought more and more powerful particle accelerators and more sensitive particle detectors. Using particle accelerators meant that particle physicists could do tests creating subatomic particles without the need to depend on cosmic rays that occur randomly. Another large number of subatomic particles were then discovered, including antiparticles that had the same mass as their counter particle, but the opposite electric charge.

Theoretical physicists studying string theory are trying to find a “theory of everything,” which joins the Standard Model with quantum mechanics. Other high-energy physicists are searching for particles that have not existed since the beginning of the universe! Searching for the Higgs Particle at the LHC The Large Hadron Collider (LHC) is the largest and most powerful particle accelerator in the world. It is located at the European Organization for Nuclear Research (CERN), which is near Geneva on the border of France and Switzerland.
