Facts of the Matter

NEW YORK TIMES / 2010
                                The Large Hadron Collider was used in 2012 to find the elusive Higgs boson particle. The complex machine at CERN, the European Organization for Nuclear Research, in Geneva, includes a huge superconducting electromagnet.

Seeing the smallest objects requires humongous energy

                                The Large Hadron Collider was used in 2012 to find the elusive Higgs boson particle. The complex machine at CERN, the European Organization for Nuclear Research, in Geneva, includes a huge superconducting electromagnet.
It is an interesting aspect of the universe and an ironic sense of unity that it requires more energy to see smaller objects. This is the result of the properties of waves in general and specifically the nature of electromagnetic waves. Read More

                                Induction cooking starts off with an alternating current, which flows through burner pads on a stove. The magnetic field that results interacts with the magnetic material in the cooking vessel, producing thermal energy. Lisa Simpson of Snohomish, Wash., uses her six-range induction stove to cook salmon and orecchiette with asparagus and leeks.

Magnetic ‘magic’ offers a cool way to charge, cook

Charging a cellphone on an induction pad seems like magic, and in a way it is. Induction is a feature of electromagnetism that Michael Faraday stated in 1831, now known as Faraday’s law. It is the basis for much of modern electrical and electronic technology. Read More

                                Machines can be made to look humanoid, but it’s highly unlikely they will take over from humans. Honda Motor Co.’s robot named Asimo, left, can walk and grip things. Internet company SoftBank’s robot, Pepper, can recognize mood swings.

Machines can be intelligent but they will never be human

Evaporation, not wind chill, leaves us cold on blustery days

The blustery winds over the past month have made us feel as if winter has set in for real. It is Hawaii, and the temperature rarely drops into the 60s, but we have “thin” blood and feel the cold more than our temperate-climate counterparts who might welcome 70 degrees in February as a cause for celebration.

                                An X-ray showing a broken arm after an accident. Richard Brill writes that most radiation is not harmful; in fact, most of it is useful. For example, there are lifesaving benefits of radiation treatment by X-rays, as well as the diagnostic use of X-rays to see inside the human body.

                                The apparent size difference in the full moon at apogee and perigee is about 12 percent, but the difference in brightness is about 30 percent.

Just about everyone knows that the moon orbits Earth once every month. What we do not commonly know is that the moon’s orbit is not circular; it is elliptical. Read More

Trendy LEDs are created with ‘doped’ materials

The hottest lights on the market today are cool light-emitting diodes, or LEDs. LEDs are made from semiconductors, which differ from conductors in the way their crystal structure holds electrons. Read More
