1. The radioactive changes of matter take place of their own accord; we can neither start, nor stop them. 2. Among the non-metals some forms of carbon are very good conductors; on the other hand, the diamond, which contains carbon, greatly resists the passage of electric current. 3. The assumption that in near future we shall be able to transform climate in some arctic regions by means of atomic energy cannot be relegated to the domain of mere fancy. 4. Powder was known to the Chinese as early as the V century. 5. In order to take advantage of the activity of sodium in liberating hydrogen, an alloy of sodium with lead or mercury is sometimes used.

ANTIPROTIONS AT SOLAR MAXIMUM. The solar wind is an electron-proton plasma blowing away from the Sun at 400 – 800 km/sec and can be thought of as a tenuous atmosphere (called the heliosphere) of the Sun extending over most of the solar system. The charged particles in this gust both envelope and are influenced by the Sun’s magnetic field. This field, because it rotates with the Sun, gets pretty tangled up. When now cosmic rays from outside the solar system venture in, they are buffeted by wind and field. During the present solar cycle of the 1990s, the configuration of the field is such that positively charged cosmic-ray protons drift into the inner heliosphere via solar polar regions and exit in equatorial regions. After the soon approaching peak period of solar activity (solar maximum), however, the Sun’s field will be reversed. Then the negatively charged cosmic-ray antiprotons preferentially follow the polar route and more easily enter the inner heliosphere to be detected by earthbound or satellite detectors. Thus in the period 2001-2010 we should see relatively more antiprotons than in the previous cycle, which is now ending. Physicists at the Bartol Research Institute at the University of Delaware have calculated when and by how much this antiproton surplus should manifest itself, telling us how well we understand the solar cycle. They have also sought ways of understanding the source of the antiprotons. Most antiprotons are made when commonplace protons strike interstellar dust, but some might have a more spectacular birth in the annihilation of dark matter or in the evaporation of primordial black holes.
WHY IS THE SAHARA A DESERT? Fossil pollen, rock art, and other hints indicate that the Sahara was much greener 6000 years ago in the mid-Holocene period. Neolithic peoples seemed to have hastened desertification at the northern and southern edges of the Sahara, but German geophysicists believe the main causes were natural. They point to the fact that precession (wobble) in the Earth’s orbit causes changes in the timing of perihelion (closest Earth-Sun approach) and our planet’s rotational tilt. These combined to promote a milder climate in most regions of the mid-Holocene Northern Hemisphere. Since then the climate has become cooler and more arid. The subtle alterations in Northern Hemisphere cooling, however, were amplified by a feedback between atmosphere and vegetation causing climate change in the Sahara region to be far more drastic than elsewhere. Indeed what occurred was “the largest change in land cover during the last 6000 years,” according to Martin Claussen. He and his colleagues have now confirmed this hypothesis with computer modeling.
THE MOST POWERFUL FREE ELECTRON LASER (FEL), as of this week, is the one at Jefferson Lab in Virginia. In an FEL amplified laser light comes from a beam of electrons passing through a cavity. The advantages of FEL’s are their tenability (with output from microwaves up into the ultraviolet), their high “duty cycle” (they deliver light continuously) and the fact that the light is produced in closely spaced picosecond bursts tied to the pulselike nature of the parent electron beam. This makes the light useful for doing fast things, such as melting metals and then watching as they refreeze into non-crystal solids, or roughening up sheets of polymer fabric so that they will accept glues or dyes. Jefferson’s FEL has an average power of 1.7 kilowatts; the best previous continuous FEL power was 11 watts.
INFLUENCE OF COSMIC RAYS ON EARTH’S CLIMATE. Do small changes in solar activity translate into climate change on our planet? One possible linkage is the sun’s influence over the local flux of galactic cosmic rays (GCR); as the solar magnetic field gets stronger, fewer cosmic rays are able to penetrate to the inner solar system and Earth. And because the GCR are the biggest ionizer of air molecules in the lower atmosphere, they might play a role in processes like cloud formation. Henrik Svensmark, a physicist now at the Danish Meteorological Institute ahs studied the connection between GCR flux, solar activity, and climate on Earth. He finds that during the past 11-year solar cycle. Earth’s cloud cover was more closely correlated with the GCR flux than with other solar activity parameters, such as solar radiance, the main energy emitted by the sun. Svensmark concludes that climate seems to be influenced by solar activity via the GCR-cloud connection. In other words, climate is partly affected by processes in deep space.
SUREFIRE QUANTUM ENTANGLEMENT, the ability to inter link two quantum particles with practically 100% certainty, has been achieved by a NIST group advancing hopes for ultrapowerful quantum computers. Previously, physicists obtained entangled particles as a byproduct of some random or probabilistic process, such as the production of two correlated photons that occasionally occurs when a single photon passes through a special crystal. Receiving entangled pars in this way is fine for tests of quantum nonlocality, but entangling a large number of quantum particles – essential for building a practical quantum computer – becomes much less likely if it is dependent on a probabilistic process. In their “deterministic enryllium ions in a magnetic field. Using a predetermined sequence of laser pulses, they entangle one ion’s internal spin to its external motion, and then entangle the motion to the spin of the other atom. The group believes that it will be able to entangle multiple ions with this process.
THE PETAWATT is the name for what is currently the world’s most powerful laser, located at Lawrence Livermore National Laboratory. It can produce pulses of 1.3 quadrillion (peta) watts for half a trillionth of a second, more than 1300 times the entire electrical generating capacity of the US, if only for a short time. At the upcoming American Physical Society Division of Plasma Physics meeting, Steve Hatchett of Livermore will describe how the laser can produce highly improved, sub-millimeter resolution images of objects through almost 6 inches of lead. Shining the laser on a gold target, Tom Cowan of Livermore and his colleagues have ejected electrons coming from a solid (K6F.02). When these electrons were made to decelerate rapidly and release high-energy photons as a result, the researchers observed the photons to induce nuclear fission of uranium-238. Although such “photofission” has been seen before, the Petawatt may allow scientists to do newly detailed studies of nuclear processes.
