1.1 Why does it hurt? The relief or avoidance of pain must be one of the major driving forces behind medical research. In this course we start the discussion about relief of pain. When we experience the sensation of pain it is likely that something is happening that the brain needs to know about, so it can direct us to whatever damage-limiting action is needed. We hurt because we have genes that constructed a body able to feel pain. Without such a mechanism it is likely that life would be much shorter,

Normal galaxies
Figure 8 shows schematically the broadband spectrum of a normal spiral galaxy. It resembles that of the Sun, although the peak occurs at a slightly longer wavelength and there are relatively greater spectral flux densities at X-ray, infrared and radio wavelengths. 3.4 Radio galaxies Radio galaxies were discovered accidentally by wartime radar engineers in the 1940s, although it took another decade for them to be properly studied by the new science of radio astronomy. Radio galaxies dominate the sky at radio wavelengths. They show enormous regions of radio emission outside the visible extent of the host galaxy - usually these radio lobes occur in pairs. The first radio galaxy to be discovered, and still the brightest, is called Cygnus A (Author(s): 1.5.7 Referencing We mentioned above that we need to reference sources to ensure we abide by copyright legislation. But there is another reason we need to give accurate references to items we use - so we can share it. Consider this scenario. A friend says they've just read an interesting article where Joshua Schachter, founder of Delicious has spoken about why it isn't a faceted search system, and you should read it. How would you go about finding it? Would you start looking in a news database, a search Elizabeth Gilbert at TED "Nurturing Creativity" Computer Basics : How to Change Wallpaper The History of Vaccines 2.1 Chemical periodicity The chemistry of the elements is immensely varied. But amidst that variety there are patterns, and the best known and most useful is chemical periodicity: if the elements are laid out in order of atomic number, similar elements occur at regular intervals. The discovery of chemical periodicity is particularly associated with the nineteenth-century Russian chemist Dmitri Ivanovich Mendeléev (Figure 16). The periodicity is represented graphically by Periodic Tables. Author(s): 2.2.1 Positive integers: denary numbers The number system which we all use in everyday life is called the denary representation, or sometimes the decimal representation, of numbers. In this system, the ten digits 0 to 9 are used, either singly or in ordered groups. The important point for you to grasp is that when the digits are used in ordered groups, each digit is understood to have a weighting. For example, consider the denary number 549. Here 5 has the weighting of hundreds, 4 has the weighting of tens and Lord Owen: British Foreign Policy after Brexit Learning outcomes After studying this course, you should be able to: understand that genes are the units of inheritance for individual characteristics and also may contribute to susceptibility to certain diseases understand the number of chromosomes that make up the human genome and where they are located within the cell understand something of the immense scale of the human genome project understand how gametes are produced by the process of meiosis a Singlet Fission II 3.4 Evaluation at the end of a project Different types of evaluation may take place at the end of a project. A common one is determining the extent to which the project outcomes have been achieved. This is often done in a meeting of the sponsor, key stakeholders and project team leaders, and sometimes informed by reports from key perspectives. An evaluation of this nature may be the final stage of the project, and the main purpose might be to ensure that the project has met all of the contracted expectations and can be ‘signed o 2.4 Collecting quantitative data How can you collect quantitative data that summarise the nature of a habitat when it is three-dimensional? How, in fact, do you collect quantitative data? Multi-storied habitats where the components have a different scale are usually recorded storey by storey, but using much the same methodology. There are two standard ways of collecting data quantitatively. The first involves recording species present within a standard area such as 10 cm × 10 cm, 0.5 m × 0.5 m, 1 m × 1 m, or 10 m × Must-Know Japanese Social Media Phrases #5 - At a Concert 8.2 Chromosome scaffolds Most of the chromosomal DNA chains within the interphase nucleus are believed to be held on a scaffold or backbone structure made from various proteins, with loops of between 20 and 200 kb extruding from attachment sites. This chromosome structure is shown schematically in Figure 40. The scaffold, as well as permitting further compaction, serves to bring the DNA together in organised regions. There are many different protein components of these scaffolds, amongst them DNA topoisomerases. Beethoven (Part 15 of 18) Age Word Problems, #1 (Algebra) - Khan Academy
Excellent video for writers of all ages. It really enforces the importance of hard work and dedication in the arts. Lecture format.
"Elizabeth Gilbert muses on the impossible things we expect from artists and geniuses -- and shares the radical idea that, instead of the rare person "being" a genius, all of us "have" a genius. It's a funny, personal and surprisingly moving talk."

"Beethoven was a German Composer and pianist. His music fell in a transitional period between Classical and Romantic music. Beethven studies with Haydn. Even after his hearing began to deteriorate he still composed, conducted and even performed his music.
