It's OK to Ask 'Em to Work: and Other Essential Maxims for Smart Managers

Also, look out for itineraries that include 'slow travel' options while overseas. Activities such as cycling, hiking and kayaking are less damaging than bus and coach travel, and will get you closer to nature. It’s challenging to avoid flying altogether, but some companies suggest low-carbon options where possible.

The convention that EM radiation that is known to come from the nucleus is always called "gamma ray" radiation is the only convention that is universally respected, however. Many astronomical gamma ray sources (such as gamma ray bursts) are known to be too energetic (in both intensity and wavelength) to be of nuclear origin. Quite often, in high-energy physics and in medical radiotherapy, very high energy EMR (in the >10MeV region)—which is of higher energy than any nuclear gamma ray—is not called X-ray or gamma ray, but instead by the generic term of "high-energy photons".

The Florida State University . Retrieved 5 March 2013. Ritter […] hypothesized that there must also be invisible radiation beyond the violet end of the spectrum and commenced experiments to confirm his speculation. He began working with silver chloride, a substance decomposed by light, measuring the speed at which different colours of light broke it down. […] Ritter […] demonstrated that the fastest rate of decomposition occurred with radiation that could not be seen, but that existed in a region beyond the violet. Ritter initially referred to the new type of radiation as chemical rays, but the title of ultraviolet radiation eventually became the preferred term. Far-infrared, from 300GHz to 30 THz (1mm – 10 μm). The lower part of this range may also be called microwaves or terahertz waves. This radiation is typically absorbed by so-called rotational modes in gas-phase molecules, by molecular motions in liquids, and by phonons in solids. The water in Earth's atmosphere absorbs so strongly in this range that it renders the atmosphere in effect opaque. However, there are certain wavelength ranges ("windows") within the opaque range that allow partial transmission, and can be used for astronomy. The wavelength range from approximately 200 μm up to a few mm is often referred to as Submillimetre astronomy, reserving far infrared for wavelengths below 200 μm.

I saw someone’s comment the other day thanking Emma for daily vlogging because she knows how much work is involved in it! Trust me, Emma is doing this for her own benefit, she’s not doing anyone a favour! L'Annunziata, Michael; Baradei, Mohammad (2003). Handbook of Radioactivity Analysis. Academic Press. p.58. ISBN 978-0-12-436603-9. Terahertz radiation or sub-millimeter radiation is a region of the spectrum from about 100GHz to 30 terahertz (THz) between microwaves and far infrared which can be regarded as belonging to either band. Until recently, the range was rarely studied and few sources existed for microwave energy in the so-called terahertz gap, but applications such as imaging and communications are now appearing. Scientists are also looking to apply terahertz technology in the armed forces, where high-frequency waves might be directed at enemy troops to incapacitate their electronic equipment. [15] Terahertz radiation is strongly absorbed by atmospheric gases, making this frequency range useless for long-distance communication.
