Free Essays on Sir Issac Newpn

Newton was an English physicist and mathematician who was born into a poor-farming family. He was not a good farmer at all. So he was sent to Cambridge to study to become a preacher. He then was influenced by Euclid to study mathematics. That was around the time when he made most of his significant discoveries. With his ignorance he waited to later in life to show the world his calculations. Which he didn’t publish most of his work. Newton suffered a mental breakdown in 1675 and was still recovering in 1679. He continued his calculations of the orbits of the planets. Again, he didn’t publish his calculations. After a while he started devoting his time to theological speculation and put the calculations on elliptical motion aside. Which he lied to Halley telling him he had lost them. Halley who then became interested in orbits, finally had become interested in orbits, then he convinced Newton to expand and publish his calculations. He spent from August 1684 till spring 1686 to this task. After he had published them in result became one of the most important and influential works on physics of all time. In book 1 of Principia, Newton opened with definitions and the tree laws of motion now known as Newton’s Law (laws of inertia, action and reaction, and acceleration proportional to force). Book 2 presented Newton’s new scientific philosophy, which came to replace Cartesianism. Finally, book 3 consisted of applications of his dynamics, including an explanation for tides and a theory of lunar motion. He then made another theory which he sooner confirmed, that when Saturn gets close to Jupiter it slows down cause of the universal gravitational pull. Then Flamsteed wrote back in great surprise that he was right. They then did really close observation to make sure they were right. These rules were stated in the Principia and proposed that (1) we are to admit no more causes of natural things such as are both true and...

How to Winterize Your Dormant Trees

How to Winterize Your Dormant Trees Trees in fall are in a state of serious change and reorganization. The tree is becoming dormant. A tree heading toward winter will sense the changing temperature and light and obey the dormancy controls built into the leaf. The mechanisms, called senescence, is what tells a tree to close down for coming winter. Tree Activity in Winter Trees may look inactive going into winter but the fact is they continue to regulate their metabolism and only slow down some physiological activities. This decrease in photosynthesis and transpiration begins a trees dormant phase. Trees still continue to slowly grow roots, respire and take in water and nutrients. Winter is a difficult time for a tree. A dormant tree still needs to be protected (winterized) to remain healthy and free from diseases and insects. The bad news is  winter weather encourages destructive pests to snuggle in and wait for spring to revive their destructive lifecycles. Small investments in properly caring for your trees can pay off big come spring. Pruning Prune dead, diseased and overlapping branches in late fall. This will form and strengthen the tree, encourages new strong growth in the spring, minimizes future storm damage and protects against overwintering disease and insects. Remember that dormant pruning has another benefit - it is easier to do during winter dormancy than in spring. Correct structurally weak branches and limbs. Remove all deadwood that is clearly visible. Properly prune branches that can touch the ground when loaded with rain and snow. Foliage and branches that are in contact with soil invite undesirable pests and other problems. Remove damaged and declining twigs, branches, and bark or any new sprouts that have grown at the tree base, or along stems and branches. Mulch and Aerate Young trees are especially vulnerable to fluctuations in temperature and moisture and need mulching protection. Mulch is good insurance that both conditions will be evenly managed during cold and drought. Mulching is a good practice for both dormant and full-growing, vegetative trees. Spread a thin layer of composted organic mulch to cover the soil several inches deep. Cover an area at least as large as the branch spread. In addition to protecting feeder roots, mulch also recycles nutrients directly to these roots. Aerate soils and compacted mulch if they are waterlogged or poorly drained. Saturated and dense soil can suffocate roots. It is critical not to damage tree roots in the soil as you do this, so work only on those few inches at the surface crust. so work only on those few inches at the surface crust. Fertilize and Water Fertilize by top dressing over the mulch with a balanced fertilizer if the essential elements are in short supply within the soil. Be sure to use nitrogen lightly, especially under large, mature trees and around newly planted trees. You do not want a vegetative flush of growth during late fall periods of warming. Large applications of nitrogen cause this growth. Dry spells in winter or hot daytime temperatures will desiccate a tree very quickly. Watering may be needed where soils are cool but not frozen, and there has been little precipitation. Winter droughts need treatment with water the same as summer droughts, except it is much easier to over-water in winter. Dormant Spray A dormant spray may be a good idea for deciduous trees, ornamentals, fruit trees, and shrubs. But remember not to spray until after you prune. Obviously, you will lose much of your effort and expense if you cut off treated limbs. Choice of chemicals is important. Dormant sprays include lime, copper and sulfur combinations to kill overwintering microorganisms. Dormant oil controls insects and their eggs. You just may need several types of sprays and oils to be effective. Avoid spraying any of this material in the hot sun as it can damage dormant buds. Get specific chemical recommendations from your local county extension agent.
