If the string theory is real, then what are strings made of? What is the difference between an echo and a reverberation? Why do many musicians wear earplugs during their performances even though the intensity of the sounds produced is lower than the threshold of pain?
What is a property of metals? Based on the band model of electron conductivity, what would you say about the effect of temperature on the conductivity of normal insulators and semiconductors? Check your ideas by finding some actual data on the conductivity of insulators and semiconduc ...
According to band theory in solid-state physics, solids have a valence band and a conduction band. For a material to conduct electrical current through it, there must be no energy gap between its valence band and conduction band. Thus, in conductors, these bands overlap, allowing electrons to...

As products of radioactive decay, astatine and the like are too scarce and ephemeral to tally directly but their abundances can be inferred from their parent elements’ well-known half-lives and decay profiles. Precious metals are heavy. Just below is a chart comparing the original eight. ...
Bracelets can be made from a variety of materials, including metals, beads, and leather. 13 What is the primary function of a bracelet? Bracelets are primarily worn for decorative purposes. 10 What is the typical closure type for a wristlet? Wristlets typically have a zipper closure for secur...
Abstract. It is shown thatexciton states exist in metals, occurring near the interband threshold in optical absorption and substantially altering the shape and strength of the absorption edge. What are self trapped excitons? Self-trapped excitons (STEs), occurring in a material with soft lattice ...
, other new bonding types are being identified. One such is the charge-shift bond.2Here the electrons are not simply shared or transferred, but undergo strong fluctuations that give rise to a bonding interaction redolent of old ideas about resonance structures in Pauling’s valence-bond theory....
