Loop the loop physics calculator12/31/2023 Let x denote the distance of P from the Centre O of the loop.Ĭonsider a very small conducting element ‘dl’ of the loop. The magnitude dB of the magnetic field due to dl is specified by the Biot-Savart law. ![]() We compute the magnetic field at the point P on this axis. The X axis is the alignment of the circle. The loop is located in the y-z plane with its Centre at the source O also radius R. If the change in force is slow, the jerk is small, and the propagation of deformation is considered instantaneous as compared to the change in acceleration.Magnetic Field at the Axis of a Current- Carrying Loop DerivationĬonsider a circular loop carrying a stable current I as shown in the figure. In movie projectors, the film advances frame-by-frame, but the projector operation has low noise and is highly reliable because of the low film load (only a small section of film weighing a few grams is driven), the moderate speed (2.4 m/s), and the low friction.Īn elastically deformable mass deforms under an applied force (or acceleration) the deformation is a function of its stiffness and the magnitude of the force. Jerk does not preclude the Geneva drive from being used in applications such as movie projectors and cams. Because of the finite thickness of the driving wheel's fork (the slot for the driving pin), this device generates a discontinuity in the angular acceleration α, and an unbounded angular jerk ζ in the driven wheel. During one cycle of the driving wheel, the driven wheel's angular position θ changes by 90 degrees and then remains constant. ![]() To minimize the effects of a jerk, curves along roads are designed to be clothoids as are railroad curves and roller coaster loops.įor a constant mass m, acceleration a is directly proportional to force F according to Newton's second law of motion:į = m a įor example, consider a Geneva drive, a device used for creating intermittent rotation of a driven wheel (the blue wheel in the animation) by continuous rotation of a driving wheel (the red wheel in the animation).These effects are not modeled in vehicle testing because cadavers and crash test dummies do not have active muscle control. When braking suddenly or during collisions, passengers whip forward with an initial acceleration that is larger than during the rest of the braking process because muscle tension regains control of the body quickly after the onset of braking or impact.When the car reaches its top speed, the acceleration has reached 0 and remains constant, after which there is no jerk until the driver decelerates or changes direction. After the launch, there is a small, sustained negative jerk as the force of air resistance increases with the car's velocity, gradually decreasing acceleration and reducing the force pressing the passenger into the seat. As the car launches from rest, there is a large positive jerk as its acceleration rapidly increases. The feeling of being pressed into the seats in a high-powered sports car is due to the acceleration.When changing gears in a car with a foot-operated clutch, the accelerating force is limited by engine power, but an inexperienced driver can cause severe jerk because of intermittent force closure over the clutch. Skilled and experienced drivers can accelerate smoothly, but beginners often provide a jerky ride. ![]() Engineers expend considerable design effort minimizing "jerky motion" on elevators, trams, and other conveyances.įor example, consider the effects of acceleration and jerk when riding in a car: Excessive jerk may also result in an uncomfortable ride, even at levels that do not cause injury. Sudden changes in acceleration can cause injuries such as whiplash. To avoid vehicle passengers losing control over body motion and getting injured, it is necessary to limit the exposure to both the maximum force (acceleration) and maximum jerk, since time is needed to adjust muscle tension and adapt to even limited stress changes. The reaction time for responding to changes in force depends on physiological limitations and the attention level of the brain: an expected change will be stabilized faster than a sudden decrease or increase of load. If the force changes too quickly, the muscles cannot relax or tense fast enough and overshoot in either direction, causing a temporary loss of control. ![]() In balancing a given force, such as holding up a weight, the postcentral gyrus establishes a control loop to achieve the desired equilibrium. Human body position is controlled by balancing the forces of antagonistic muscles. See also: Human tolerance of g-force and How human physiology processes and responds to motion

Origin of species12/31/2023 Given enough time, more changes will accrue. The composition of the population will have changed. Indeed, at one point, he humorously states anyone who has read his friend Charles Lyell’s book Principles of Geology and is still unconvinced about the great age of the earth might as well close Origin right away.ĭarwin’s great theory is brilliant in its simplicity: individual organisms within a species vary those with beneficial variations will have a better chance of competing for limited resources, and of passing on those beneficial variations to future generations over time, these beneficial variations will become more widespread in local populations. But he realises some of his audience-especially some of the old guard-will not be able to accept his evidence and line of reasoning. He knows his views will be seen as controversial by some of his contemporaries, and he’s out to convince. That should be a good enough reason for anyone to read it.ĭarwin describes his masterpiece as ‘one long argument’. ![]() ![]() To read Origin is to have the theory explained to you by the man himself. Darwin’s great theory of evolution by means of natural selection forms the foundation of modern biology. True, some of the language is occasionally heavy going-Darwin wrote in haste, had a thing for double negatives and rogue commas, and occasionally embarked on convoluted, heavily nested sentences requiring several deep breaths to read out loud-but, minor stylistic concerns aside, over a century and a half after its publication, Origin is still a rewarding read for anyone wanting to get inside the mind of one of the most important figures in the history of science. The resistances as well as the enthusiasms of the first readers cast light on recent controversies, particularly concerning questions of design and descent.As revolutionary scientific works go, Charles Darwin’s On the Origin of Species is remarkably accessible to the ordinary reader. The present edition provides a detailed and accessible discussion of his theories and adds an account of the immediate responses to the book on publication. that individuals having any advantage, however slight, over others, would have the best chance of surviving and of procreating their kind?' Darwin's prodigious reading, experimentation, and observations on his travels fed into his great work, which draws on material from the Galapagos Islands to rural Staffordshire, from English back gardens to colonial encounters. Includes a Register of Writers referred to in the text of the Origin, a Glossary of Scientific Terms and an Index.Ī Postscript to the Introduction considers in detail the first reactions to the work and Darwin's responses to criticism it considers the controversy in the light of the recent revival of Creationism and Intelligent Design and shows how little has changed. Her wide-ranging introduction considers the development of Darwin's ideas, the scientific context, the nature of his theories and the impact of his work on his contemporaries. Charles Darwin revolutionized our ideas about the natural world and our place in it by introducing the concepts of natural selection and survival of the fittest, and his ideas still provoke controversy today.Įditor Gillian Beer has writtten extensively about Darwin and about scientific writing in its cultural context.

Snail pictures12/31/2023 ![]() These snails do have a distinct look compared to other types of freshwater snails. ![]() The primary difference comes down to color. Generally, all Rabbit Snails have similar physical characteristics. For example, there are Black Rabbit Snails, Red Rabbit Snails, and so on. Typically, they’re named after specific coloration of their shells or body. AppearanceĪs we mentioned earlier, there are several types of Rabbit Snails available. During this time, they may retreat into their shell. These snails are known to go through random bouts of rest. A poorly maintained aquarium can cause unnecessary stress that shortens their lifespan significantly, so make sure to stay on top of water conditions!Īuthor Note: If you do see your snail lying on the bottom of the tank motionless, wait a bit before you get concerned. They are particularly sensitive to high ammonia and nitrate levels. Some specimen have even been able to live past 3 years in optimal conditions. Like any other creature you put in your tank, the snails’ life expectancy can vary based on their quality of life. In captivity, the average Rabbit Snail lifespan has been observed to be somewhere between 1 and 3 years. With good water conditions and a healthy diet, these snails can continue to grow and reach their full potential. Regardless of the type of Rabbit Snail you get, it’s important to provide the best care possible. Though, most of their care requirements are the same. There are several individual species available. Technically speaking, the term “Rabbit Snail” refers to a larger genus of freshwater snails. Naturally inquisitive, these snails are not shy and can be seen meandering tanks at all hours of the day!Īlso known as the Elephant Snail (some even call them the Bunny Snail), these critters originally come from Sulawesi, Indonesia. They’re unique snails with some distinct personalities. However, those that are lucky enough to own them usually have nothing but good things to say. They were first introduced to the market around 2007. Rabbit Snails ( Tylomelania) are a relatively new freshwater invertebrate to grace the fish-keeping community.

The story behind the remembrance poppy12/31/2023 ![]() The poppy is a symbol of remembrance and peace in the united kingdom which has been worn since 1921 to remember the war dead. The tradition has also spread to many other countries and remains a symbol of remembrance and hope. The red poppy became synonymous with the fallen troops during the first world war and has remained a symbol of their sacrifice ever since. The poppy was also adopted as the official memorial flower of the VFW. The American Legion started selling red paper poppies in 1921 to raise funds to help disabled and hospitalized veterans. She told them to wear the poppy as a tribute to the fallen. Hearing that the British Legion wanted to buy Remembrance poppies made in Britain, George Howson proposed that the poppies should be made by disabled war. In 1918, she bought all of the poppies at New York City’s Wanamaker’s Department Store and handed them out to businessmen she worked with. She conceived of the idea of selling silk poppies as a fundraiser, and, in 1921, her efforts resulted in the poppy being adopted as a symbol of remembrance for war veterans by the American Legion Auxiliary and by Earl Haig's British Legion Appeal Fund (later The Royal British Legion). John McCrae.Įven though the land where WWI was fought turned bleak and barren, the red poppy managed to flourish and McCrae was inspired by it.Īmerican humanitarian Moina Michael read the poem and decided to make the poppy a symbol of remembrance. The wars for which the black flowers are worn in remembrance of include the Napoleonic, Crimean and Boer Wars, as well as both World Wars. The flower was mentioned in the famous WWI poem called, “In Flanders Fields,” and was written by Canadian officer Col. But do you know what the poppy stands for? You may see veterans organizations like the American Legion and the Veterans of Foreign Wars VFW asking for donations in exchange for a red paper poppy. AuthorWrite something about yourself.
