Agency in Iran. Along with these public space programs, many companies produce technical tools and components such as spaceships and satellites. Some known companies involved in space programs include Lockheed Martin, Northrop Grumman, EADS, and Boeing. These companies are also involved in other areas of aerospace such as the construction of aircraft. Many countries have air transport companies, such as Air France and Air India. Biotechnology-Biotechnology is technology based on biology, especially when used in agriculture, food science, and medicine. United Nations Convention on Biological Diversity defines biotechnology as:[1] Any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use. Biotechnology is often used to refer to genetic engineering technology of the 21st century, however the term encompasses a wider range and history of procedures for modifying biological
biomass as being different types of bacteria, fungus, viruses and types of algae. These microorganisms are interdependent at many times and the amount of them can be influences by many variable that range from climatial to mankind.

in winning general acceptance. The collected evidence of The Origin of Species was sufficient to persuade most biologists that this was the key that they had been looking for. Quite a few scientists held out, notably Louis Agassiz, but the younger generation of students coming into the field seem almost without exception to agree to the adopted theory. Within a few decades, evolution through natural selection was a fundamental paradigm of biological thought. The development of biology through the century since that time has not essentially altered the situation. Alot of changes have been introduced, or at least debated. Once genetics was more fully understood, it was realized that major steps in specification might just owe more to favourable mutations than to the regular process of variation. But the introduction of mutation did not change the principle of natural selection. Natural selection, as Darwin saw it, simply can not be ignored
NEUROBIOLOGY AUXILLARY GLOSSARY ACETYLCHOLINE – A neurotransmitter in both the brain and peripheral nervous system* (PNS). In the brain it helps regulate memory, whilst it controls the actions of skeletal and smooth muscle within the PNS. ACTION POTENTIAL – An electrical phenomenon which occurs when a neurone is activated and temporarily reverses the electrical state of its interior membrane from negative to positive. An electrical charge travels along the axon to the neurone’s ending (terminal) where it triggers the release of a neurotransmitter* and then disappears. ADRENALINE (U.S. - Epinephrine) – A hormone released by the adrenal medulla* and a neurotransmitter acting at the level of the autonomic nervous system and the brain. ADRENAL CORTEX – The outer layer of the adrenal, a small endocrine gland located near the kidney. It produces and secretes several hormones* (corticosteroids) e.g. cortisol. I

What is the real meaning of life? Why prefer one thing to another? Can we trust observation? It’s raining outside - how do you know it is? I can see it’s raining. How to convince yourself its raining? A good reason to doubt - 49 other peaople have the same opinion. Falsifiable → possible; not falsified World disappeared in 2012 and got recreated 3 secs later → unfalsifiable - cannot prove it’s true/wrong, cannot provide any tests to prove it.

Education Education is so multifaceted that it is difficult for me to know where to begin discussing it, or how to prioritize the many factors. Relaying my own experience is easy: I had a standard classroom approach, supplemented by inordinate reading. In only the briefest and least memorable instances did I receive any individual tutoring. Education is commonly thought of as the job of schools. Adults cry "educate our children!" Everyone has opinions about the best way to do the job. It is of urgent importance, and all the numerous factors are much studied, debated, and new (or old) ideas continually tested or retested. Some people say "it's as simple as . . . " and then name their pet peeve or passion. My view is not of an education specialist, but of one who loves sharing what I learn, and owes much to educators. Since I don't have an educational theory neatly worked-out, nor an outline
