TSI Essay Contest winning entry – Teleportation and You

TELEPORTATION AND YOU!

Every time I get to watch Star trek or devour a page or two of HG WELL’s charismatic Sci-Fi Novels, it seems as though I have been sucked into a brand new universe where humans behaved like sub atomic particle, zipping –zapping, replicating, combining, teleporting and doing chores at the speed of light, where science and Fiction co-exist peacefully.

Science has been this area of education which has always intrigued me. Science is everywhere, you can understand it, you can feel it and most importantly, you can use it to make life a lot easier. Being more precise, PHYSICS, the most fundamental reasoning behind the functioning of every single object in this universe – Minute as a quark, humongous as a black hole. (to save your time and precious WHITE PAPER, allow me to time warp into the future and reach the point of discussion where i would have finally reached ,but sluggishly, gradually , tasting every morsel of the Scientific temper boiling within me!) But one isolated blemish in scientific fabric, that being so ferocious and hard hitting on this beautiful brain! At the same time, the intriguing and DANGEROUSELY attractive world of Quantum Mechanics that opens up our path to the fictional elements of science, including TELEPORTATION, that for years, has been considered   a fragment of human imagination.

When I grow up to become a scientist , maybe I won’t be able to teleport people but at least , I can guarantee a thunderous start up to this new division of science. Teleportation is usually considered vanishing of Super heroes on earth and reappearance on some other bizarre location in the vast outer space. (the primary STAR TREK definition) But there is more to it in science; Teleportation refers to travelling large distances yet not LITERALLY covering that distance manually! In simpler words, if you are on earth and wish to reach the Moon, by approximately you will have to travel 3, 84,400km by a Space ship, but what if you get to reach the moon never having to travel the great expanse of space in between!   And my friend that is what H.G. Wells called … TELEPORTATION. This can be achieved by usage of a segment of Quantum mechanics , the so called QUANTUM ENTANGLEMENT ’ which hilariously enough had been called ‘ spooky Action At A Distance’ by the great Albert Einstein after a   lifelong debate with Neils Bohr who seemingly had the better of it, with a studier scientific argument. Precisely ‘entanglement’ refers to a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently—instead, a quantum state may be given for the system as a whole. Demonstrating with a example , Let’s say you have two rotating circles with six to eight colored sectors ( Alternate colors of Red and Blue ) , the first one being placed at your home and the other on some useless Asteroid floating in the Andromeda galaxy. You rotate the circle at your home and let’s assume it halts at a blue colored sector, then without any doubt you can say that the other circle which had been entangled (Quantum) will halt at a red colored sector. And my dear reader, a group of scientist has already been successful in Teleporting a particle 3 meter apart from its initial position with 100% accuracy, though this is the very first brick in this tower of scientific advancement. It has laid down a strong base for futuristic theory to rely upon.

Teleporting human will be the biggest challenge and I wish to achieve it by building a Teleporting arena (similar to that in Star trek) that can make human movement a lot easier, cheaper and convenient. This arena shall consist of Teleporting tubes that can increase and breakdown the human bodies in to a clump of atoms, which further shall be entangled with atoms, placed in a similar tube far away. All the information, including genetic data shall be replicated on the atoms placed in destination tube and the process shall continue the other way round and lo! We will find our self at a desired destination in negligible time! Though, we will have to lose our previous atoms, the original ones that our body was made up off but anyway it does not really matter because it is the genetic information of our body that really defines us as HUMANS, our intelligence …. Our capability.

Osteoarthritis

Osteoarthritis is the most common type of arthritis and is seen especially in old age. Sometimes it is also called degenerative joint disease. People with osteoarthritis usually have joint pain and stiffness. Unlike other forms of arthritis, such as rheumatoid arthritis, Osteoarthritis affects only joint functions. Although Osteoarthritis becomes more common with age, younger people can also develop it, usually as a result of joint injury, a joint malformation, or a genetic defect in a joint cartilage. Both men and women can have the disease. Before age 45, more men than women have osteoarthritis; though it is more common in women. It is also more likely to occur in people who are overweight and in those who do jobs that stress a particular joint. Osteoarthritis most often affects the knees, and hips. It can also affect the hands (at the end of the figures and thumbs), and spine (neck and lower back). With severe osteoarthritis, the cartilage wears away. Spurs grow out from the edge of the bone, and synovial fluid accumulates. Altogether, the joint feels stiff and sour.

Pic: Normal Joint Vs Joint of Osteoarthritis

The Warning Sign of Osteoarthritis:

  • Stiffness in a joint after getting out of bed or sitting for a long time.
  • Swelling in one or more joints
  • Crunching feeling or the sound of bone rubbing on bone.

 

  1. Diagnosis:

 

Clinical History:

The doctor begins by asking the patient to describe the symptoms, and when and how the conditions started as well as how the symptoms have changed over time. Accurate answers to these questions can help the doctor make a diagnosis and understand the impact of the disease has done to his life.

Physical Examination:

The doctor will check the patient’s reflexes and general health, including muscle strength. The doctor will also examine the bothersome joints and observe the patient’s ability to walk, bend, and carry out activities of daily leaving.

X-rays:

X-rays can help the doctor to determine the effect of the arthritis a person has and how much joint damage has been done.

Magnetic Resonance Imaging (MRI):

It provides high resolution, computerized images of internal tissues.

 

  1. Role of Osteoarthritis Treatment:
  • To control pain.
  • To improve joint function
  • To maintain normal body weight
  • To achieve a healthy lifestyle

 

  1. Treatment Approaches to Osteoarthritis:
  • Exercise
  • Weight Control.
  • Rest and relief from stress on joints.

 

  • Excersice:

Research shows that exercise is one of the best treatments for osteoarthritis. Exercise can improve mood and outlook, decreases pain, increases flexibility, strengthen the heart and improve blood flow, maintain weight and promote general physical fitness. Exercise is also inexpensive, and if done incorrectly has few negative side effects. The amount and form of exercise prescribed will depend on which joints are involved, how stable the joints are, and whether a joint replacement has been done. Walking, swimming and water aerobics are few popular types of exercise for people with osteoarthritis.

  • Strengthening Exercise:

This exercise strengthens muscles that support joints affected by arthritis. They can be performed with weights or with exercise bands, inexpensive device that adds resistance.

  • Aerobic Activities:

These are exercises, such as brick walking, or low- impact aerobics, that gets your heart pumping and keep your lungs and circulatory system in shape.

  • Range- of -motion activities: This keeps your joints flexible.
  • Balance and agility exercise: This helps you maintain daily living skills. Ask your Physiotherapist what exercise is best for you. Ask for guidelines on exercising when a joint is sore or if swelling is present.

 

  • Weight Control:

Osteoarthritis patients who are overweight or obese should try to lose weight. Weight lose can reduce stress on weight-bearing joints, and increase mobility. A firm decision can help you develop healthy eating habits. A healthy diets and regular exercise help reduce weight.

 

  • Rest and relief from stress on joints: Treatment plans include regularly scheduled rest. Patient must learn to recognize the body’s signal, and know when to stop or slow down. This will prevent the pain caused by overreaction. Although pain can make it difficult to sleep, getting proper sleep is important for managing arthritis pain. If you have trouble sleeping, you may find the relaxation techniques. Some people find relief from special footwear and insoles that can reduce pain and improve walking or from using canes to take pressure off painful joints. They may use splints or braces to provide extra support for joints and \or keep them in proper position during sleep or activity. Splints should be used only for limited period of time because joints and muscles need to be exercised to prevent stiffness and weakness. If you need a splint and occupational Therapist or doctor can help you get a properly fitted one.

 

  1. Physiotherapy: People with osteoarthritis may find many new ways to relief pain. Below are some examples-
  • Heat and cold: Heat or cold (or a combination of the two) can be useful for joint pains. Heat can be applied in the number of different ways-

With warm towels, Hot packs or a warm bath or shower to increase blood flow and ease pain and stiffness. In some cases, cold packs(bags of ice or frozen vegetables wrapped in a towel) , which reduce inflammation, can relieve a pain or numb the sore area.(check with a doctor or physical therapist to find out if heat or cold is the best treatment)

  • Transcutaneous electrical nerve stimulation (TENS): TENS is technique that uses a small electronic devise to direct mild electric pulses to nerves endings that lie beneath the skin in the painful area. TENS may relieve some arthritis pain. It seems to work by blocking pain messages to the brain and by modifying pain perception.
  • Massage: In this pain relief approach a massage therapist will lightly stroke and/or knead the painful muscles. This may increase blood flow and bring warmth to a stressed area. However, arthritis stressed joints are sensitive, so the therapist must be familiar with the problems of the disease.

Supermoon Total Eclipse

The Sep 27/28 Lunar eclipse was intently watched all over the world for it was a rare occurrence indeed. It was a total lunar eclipse, which was a part of a series of eclipses called a tetrad, at a time when it was closest to the earth in its orbiting path.

Pictures sent by our readers

Only about one in three lunar eclipses are total lunar eclipses. Every once in a while, four total lunar eclipses happen in a row. This is called a lunar tetrad.

According to NASA, the current century – 2001 to 2100 – will have eight tetrads. They have only occurred 5 times in the 1900s -1910,1928,1946,1964,1982

Supermoon

Fig: Total lunar eclipse

 

supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth. The term “supermoon” is not astronomical, but originated in modern astrology. The technical name is the perigeesyzygy of the Earth-Moon-Sun system. A full moon at perigee is visually larger up to 14% in diameter (or about 30% in area) and shines 30% more light than one at its farthest point, or apogee.

 

Blood Moon is not really a scientific term either and is sometimes used to describe a Total Lunar Eclipse. When the Earth casts its shadow on a Full Moon and eclipses it, the Moon may get a red glow

The red color of the moon is due to the Rayleigh scattering of sunlight through the Earth’s atmosphere, the same effect that causes sunsets to appear red

 

Like solar eclipses, lunar eclipses tend to occur in 18 year long cycles called Saros cycles. Lunar eclipses separated by a Saros cycle share similar features, including time of the year and the distance of moon from earth. Eclipses that are separated by a Saros cycle are included in a Saros series.

 

The September 27/ 28, 2015 Lunar Eclipse belonged to Saros Series 137. It was the 28th eclipse and the last total lunar eclipse in a series of 81 lunar eclipses. The series began with a penumbral eclipse on December 17, 1564 and will end with another penumbral eclipse on April 20, 2953.

 

The next Super moon eclipse of the tetrad is slated to happen on October 8, 2033.
