The present is the time that is associated with the events perceived directly, not as a recollection or a speculation. It is often represented as a hyperplane in space-time.
Present as time- conscious experience of duration, the period during which an action or event occurs. Time is also a dimension representing a succession of such actions or events. Time is one of the fundamental quantities of the physical world, similar to length and mass in this respect. The concept that time is a fourth dimension—on a par with the three dimensions of space: length, width, and depth—is one of the foundations of modern physics. Time measurement involves the establishment of a time scale in order to refer to the occurrence of events. The precise determination of time rests on astronomical and atomic definitions that scientists have established with the utmost mathematical exactness.
Physicists agree that time is one of the most difficult properties of our universe to understand. Although scientists are able to describe the past and the future and demarcations such as seconds and minutes, they cannot define exactly what time is. The scientific study of time began in the 16th century with the work of Italian physicist and astronomer Galileo Galilei. In the 17th century English mathematician and physicist Sir Isaac Newton continued the study of time. A comprehensive explanation of time did not exist until the early 20th century, when German-born American physicist Albert Einstein proposed his theories of relativity. These theories define time as the fourth dimension of a four-dimensional world consisting not just of space but of space and time.
Several ways to measure time are in use today. Solar time is based on the rotation of Earth on its axis. It makes use of the Sun’s apparent motion across the sky to measure the duration of a day. Sidereal time is also based on Earth’s rotation, but uses the apparent motion of the “fixed” stars across the sky as Earth rotates as the basis for time determination. Standard time, the familiar clock time most people use in everyday life, is based on the division of Earth’s sphere into 24 equal time zones. Dynamical time—formerly called ephemeris time—is the timescale of astronomy. Astronomers use the orbit of Earth around the Sun, as well as the orbital motions of the Moon and the other planets, to determine dynamical time. Atomic time is based on the frequency of electromagnetic waves that are emitted or absorbed by certain atoms or molecules under particular conditions. It is the most precise method for measuring time.
The measurement of time passage probably began with the concepts of past, present, and future. Throughout history humans have used various celestial bodies—that is, the Sun, the Moon, the planets, and the stars—to measure the passage of time. Ancient peoples used the apparent motion of these bodies through the sky to determine the seasons, the length of the month, and the length of the year. Humans created the sundial and the hourglass to measure time. (http://encarta.msn.com)
“Everything that has been will be, everything that will be is, everything that will be has been.” Eugène Ionesco (1909 – 1994)
“The future is made of the same stuff as the present.” Simone Weil (1909 – 1943)
“In other words, it is quite true that the past haunts us; it is the past’s function to haunt us who are present and wish to live in the world as it really is, that is, become what it is now.” Hannah Arendt (1906 – 1975)
“The Past lies upon the Present like a giant’s dead body.” Nathaniel Hawthorne (1804 – 1864)
“We are always acting on what just finished happening. It happened at least one thirtieth of a second ago. We think we’re in the present but we aren’t. The present we know is only a movie of what happened in the past.” Ken Kesey (1935 – 2001)
“The now, the here, through which all future plunges to the past.” James Joyce (1882 – 1941)
“The real universe. That’s the present moment. The past is no good to us. The future is full of anxiety. Only the present is real—the here-and-now. Seize the day.” Saul Bellow (1915 – 2005)
The present as an image is something that will not be there later. At least that is my interpretation. So there are fungi, spiderwebs, fallen leaves, and, flowers, all things with short life spans in location.
Fungi
This fungi is an essential part of any ecosystem. The mushroom plant itself is actually an extension of the tips that make up this underground fungi network, as the tips have a tendency to become dry. After a good rain, the tips soak up excess moisture and thereby grow into the mushrooms we see.
As quickly as a patch of mushrooms appears, so it disappears once the moisture dries off. The short time that the mushroom body appears above ground is time enough for spore structures to detach and replant in a new locale.
spider Webs
If all that is a little confusing, is it as strong as steel, stronger than steel or less strong, is it stronger than Kevlar or not, perhaps we can find some facts somewhere. The truth is it depends on how you measure it and what condition the silk is in. Silk absorbs moisture (a property given it by the large amount of the amino acid Alanine it contains). The more water silk contains the less brittle and the more elastic it is. The range is from about 30% to 300% elasticity depending on the amount of water it contains. Thus we can see that changing the humidity of the environment the silk is spun in, and the length of time it exists in that environment before it is tested will effect the results of the tests.
Leafs
All that is known is that at around 12 hours of daily sunlight, photoperiodism triggers leaf senescence in trees.
Flowers
Annuals
Annual wildflowers are the ones which grow quickly from seed, bloom usually for a long period (about two months, on average), and then die with the first hard frost. This means annual wildflowers live only one growing season. They are propagated by dropping their seeds as their flowers fade. This tells you that if you know of an annual that “came back” for a second year after a winter, it simply re-grew the second year from seed it produced the year before. This is called “self-sowing, and usually happens only when annual seed falls on bare ground. Most wild annuals are native to open spaces, rather than areas that are, or were originally, wooded. Popular wild annuals are the European red poppy and North America’s plains coreopsis.
Perennials
Perennial wildflowers are the ones that “come back” each year from the same roots, forming larger and larger clumps with more and more flowers as they age. From seed, they germinate more slowly than most annuals, and make minor above-ground growth during their first growing season. Bloom usually begins their second growing season, and a perennial’s season of bloom is usually much shorter than that of an annual. (The average perennial blooms for about two weeks.) Examples of perennials are common daisies, purple coneflower, St. Johnswort, and the goldenrods. Some perennials live to return year after year for decades or even centuries. Others are what botanists call “short-lived”, which usually means the plant persists for less than five years.
Biennials
The third and smallest group of wildflowers are the biennials. These plants have a two-year life-cycle. Like perennials, they normally do not bloom their first year, but bloom and seed profusely– for a comparatively long period– their second. Common examples of biennials are our common roadside weed, Queen Anne’s lace, and one of North America’s most popular native flowers, the black-eyed Susan.
