The ISS is used mostly for scientific research in the unique environment of microgravity. Gravity influences many physical processes on the blue planet we call home. For example, gravity alters the way that atoms come together to form crystals. Aboard the ISS, experimenters can develop bigger and...
which uses floating-gate transistors to store electrical charges that represent data. Another type is ferroelectric RAM (FeRAM), which uses a ferroelectric material to store information using the polarization of its atoms. There are also other emerging technologies like magneto resistive RAM (MRAM) ...
Although there are many types of lasers, all have certain essential features. In a laser, the lasing medium is “pumped” to get the atoms into an excited state. Typically, very intense flashes of light or electrical discharges pump the lasing medium and create a large collection of excited-...
Consider heat emitted by the sun. The heat is converted into IR, which streams through empty space. When the IR reaches Earth, it hits atoms in the atmosphere, transferring energy and warming the planet. “You have heat converted into electromagnetic waves, which is being converted back into ...
