Magenta Ain't A Colour

Magenta Ain't A Colour
A beam of white light is made up of all the colours in the spectrum. The range extends from red through to violet, with orange, yellow, green and blue in between. But there is one colour that is notable by its absence. You should have seen a green afterimage, but why is this significant? The afterimage always shows the colour that is complementary to the colour of the image. Complementary colours are those that are exact opposites in the way the eye perceives them. It is a common misconception that red is complementary to green. All the colours in the light spectrum have complements that exist within the spectrum – except green. The light spectrum consists of a range of wavelengths of electromagnetic radiation. When our eyes see colours, they are actually detecting the different wavelengths of the light hitting the retina. If the eye receives light of more than one wavelength, the colour generated in the brain is formed from the sum of the input responses on the retina. -Biotele

The Top 10 Psychology Studies of 2010 The end of 2010 fast approaches, and I'm thrilled to have been asked by the editors of Psychology Today to write about the Top 10 psychology studies of the year. I've focused on studies that I personally feel stand out, not only as examples of great science, but even more importantly, as examples of how the science of psychology can improve our lives. Each study has a clear "take home" message, offering the reader an insight or a simple strategy they can use to reach their goals , strengthen their relationships, make better decisions, or become happier. 1) How to Break Bad Habits If you are trying to stop smoking , swearing, or chewing your nails, you have probably tried the strategy of distracting yourself - taking your mind off whatever it is you are trying not to do - to break the habit. That's because habit-behaviors happen automatically - often, without our awareness. J. 2) How to Make Everything Seem Easier J. 3) How To Manage Your Time Better M. 4) How to Be Happier J.

typing lessons This is keybr.com, a web application that will help you teach touch typing. Touch typing is typing without using the sense of sight to find the keys. A person possessing touch typing skills will know their location on the keyboard through muscle memory. This is a short tutorial that will explain how does this application work. You can use the left and right arrow keys to navigate through these slides. This tutorial is based on these few principles: No boring, repetitive exercises. Initially it starts generating words from a small subset of the most frequent letters of the alphabet. When you are typing these words, keybr measures time to type a key for every letter in that subset. Once you familiarize yourself with the current subset of letters, the algorithm expands it, including more and more letters to it. The algorithm can also artificially rearrange letter frequencies, putting emphasis on the letters with the worst time to type measure. This is the text board. This is virtual keyboard.

Banana equivalent dose Informal measurement of ionizing radiation exposure Banana equivalent dose (BED) is an informal unit of measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana. Bananas contain naturally occurring radioactive isotopes, particularly potassium-40 (40K), one of several naturally occurring isotopes of potassium. One BED is often correlated to 10−7 sievert (0.1 μSv); however, in practice, this dose is not cumulative, as the potassium in foods is excreted in urine to maintain homeostasis.[1] The BED is only meant as an educational exercise and is not a formally adopted dose measurement. The banana equivalent dose is an informal measurement, so any equivalences are necessarily approximate, but it has been found useful by some as a way to inform the public about relative radiation risks.[3] Source of radioactivity [edit] Radiation from other household consumables

13 Unique Punctuation Marks You Never Knew Existed With the rise of technology, 140 character tweets and SMS shorthand texts ("BWl! Aamof afaik gonna mari him cuz im in luv wit him!" = "Bursting with laughter As a matter of fact, as far as I know I'm going to marry him - because I'm in love with him.") the English language is under attack. But fear not, we're going to arm you with 13 of the most deadly and pretentious punctuation marks in the history of the written word, soon enough you'll be able to come across as a well-educated and well-rounded private school Boffin. Plus you'll sound cool doing it, how could using a symbol called the 'Interrobang‽' not be awesome right? Despite it's epic name 'Asterism' and great design, its use is rather underwhelming. It's also known as an Obelisk. It's easy to think this is just your typical slash but don't be fooled. This little symbol actually has 3 other names, it can be called a Wedge, an Up-Arrow and even a Hat. The best of both worlds right? The best buddy of the Exclamation Comma.

Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature, which has the value 1.416785(71)×1032 kelvin.[3] This value is assumed to be the highest temperature because conventional quantum physics relies on Planck's law which implies a lower limit for the wavelength of electromagnetic radiation. The models of the origin of the universe based on the Big Bang theory assume that the universe has passed through this temperature about 10−42 seconds after the Big Bang as a result of enormous entropy expansion.[3] Above ~1032K, particle energies become so large that there is no existing scientific theory for the behavior of matter at these energies. Gravitational forces between them would become as strong as other fundamental forces, requiring a hypothetical theory of everything for description.[4] See also[edit]
