Penemu Mesin Jet

SIR FRANK WHITTLE (1907-1996)

Kita semuanya tahu yang namanya mesin jet? Ya, Mesin Jet sendiri adalah sebuah mesin yang biasa digunakan untuk pesawat terbang untuk keperluan militer ataupun komersil. Mesin Jet ini membuat sebuah kendaraan dapat bergerak dengan sangat cepat. Karena sangat cepatnya maka kebanyakan mesin jet lebih banyak dipakai pada pesawat terbang.

Sir Frank Whittle adalah orang yang menemukan mesin jet pada tahun 1937, dia adalah seorang opsir pada Angkatan Udara Kerajaan Inggris (Royal Air Force). Sir Frank Whittle lahir pada tanggal 1 Juni 1907 di Coventry, Inggris. Lalu di tahun yang sama, mesin jet sudah diciptakan tersebut bahkan sudah diuji coba di sebuah pabrik di Jerman yang bernama Heinkel pada bulan Maret tahun 1937. Mesin jet ciptaan Sir Frank Whittle kemudian dikembangkan oleh seorang Jerman dan juga sekaligus merupakan desainer dari mesin jet pertama yang bernama Dr. Hans von Ohain.

Kemudian pada tahun 1940, Sir Frank Whittle mengajukan sebuah permohonan paten secara luas. Lalu Sir Frank Whittle mendapatkan perhatian dan juga dorongan dari Kementrian Udara dan juga dari industri. Lalu setelah Sir Frank Whittle mendapatkan dukungan dari sebuah bank untuk melakukan sebuah investasi usaha, di tahun 1963 Powers Jets di bangun dan Sir Frank Whittle diberi tugas oleh perusahaan untuk tugas militer khusus untuk menyusun desain dan juga pengembangan mesin jet miliknya (Sir Frank Whittle).

Pada tahun selanjutnya, karena eksperimen pertama memiliki banyak sekali masalah, maka diperlukan untuk rekonstruksi ulang untuk beberapa kali. Pada tahun 1939, akhirnya penemuan atau eksperimen Sir Frank Whittle tersebut diterima dengan baik oleh Kementrian Udara karena Sir Frank Whittle telah memperbaiki mesin tersebut sehingga mesin yang dihasilkan dengan 10 (Sepuluh) ruang pembakaran dilakukan dengan cukup baik. Kini mesin jet temuan Frank Whittle sudah banyak dipakai oleh pesawat-pesawat baik itu pesawat komersil ataupun pesawat tempur. 

Sir Frank Whittle meninggal karena penyakit kanker paru-paru pada tanggal 9 Agustus 1996 di rumahnya di Columbia, Maryland. Dia dikremasi di Amerika dan sebagian abunya diterbangkan ke Inggris dimana sebagian lagi ditempatkan di tugu peringatan di sebuah gereja di Cranwell. Sir Frank Whittle, sang Penemu Mesin Jet kini dianggap sebagai salah satu tokoh paling berjasa dalam dunia penerbangan atau kedirgantraan berkat mesin temuannya. *** [EKA | DARI BERBAGAI SUMBER | WIKIPEDIA]

A comet riding Robot approaches the Sun.

The space scientists are looking forward with great anticipation because today a riding comet laboratory robot is heading the Sun. The robot, named Philae landing on Comet 67P November last year and its parent laboratories, Rosetta, orbiting nearby. Scientists hope the mission will help them find a more distant origin of the universe.

Next Thursday, Comet 67P will reach its closest distances to the Sun, which is 186 million kilometers from the Sun. The heat of the Sun has made the comet's surface hot for weeks to catapult the particles of gas and dust. The sensors at Philae and Rosetta will analyze the particles of rare molecules, in particular that may be hidden under a layer of a comet that is usually filled with ice.

Because of the great distances, scientists may have to wait weeks or even months until the data sent back to Earth. As we are knew, The Rosetta mission was launched March 2, 2004 by the European Space Agency from its base in French Guyana.  It arrived at the comet in August 2014. When the robot lab landed, it bounced into a ditch where it was in shadow and not able to recharge its batteries.  It was able to send data before going into standby mode.

As the comet neared the sun the lab's batteries recharged and in June it sent a two-minute message.  But since July 9 Philae has been silent. As Comet 67P leaves its close encounter with the sun, Rosetta will try to re-establish communications with the lab.  Ground teams will be keeping their fingers crossed. *** [EKA | FROM VARIOUS SOURCES | VOANEWS]

World's smallest electric car can be parked in your bag

An engineer from Japan, Kuniako Saito, along with his team, Cocoa Motors, has recently launched the smallest electric car in the world, named 'WalkCar'. One of the advantages of four-wheel vehicles weighing between 2-3 kg is not requiring complex parking lot, just lift and then put into a hand bag or even a backpack.

The 'WalkCar' is small enough to fit in a backpack, and has a top speed of 10 km/h. To steer, the user just shifts their weight. (Picture from: http://dailym.ai/1IrHiY3)

As quoted by Daily Mail on Monday, August 10, 2015, the operation of the portable vehicle was also quite simple. After pushed the 'on/off' button to activate it, and user climbed up on it, then drive. To control simply by moving the body, similar to a skateboard. So anything to stop it, users simply lowered one foot and stepped on to the ground.

This vehicle is made of strong aluminum material but lightweight. Its power source comes from an electric motor that uses electricity intake source of lithium ion batteries.

The lightweight aluminum board is stronger than it looks, and can take loads of up to 120 kg (265 lbs). (Picture from: http://dailym.ai/1IrHiY3)

Its weight is very light and it ranged between 2-3 kg. The weight difference depending on the type based on usage, the indoors type, weighs only two kilograms and the outdoors used three kilograms.

If the vehicle's battery is fully charged can roam up to a distance of 12 km (7.4 miles), and the speed reaches 10 km/h (6.2 mph). Although lightweight and made of aluminum, but able to support the weight up to 120 kg (265 lbs). For battery charging is quite easy, because it can be done in the home electrical installation. The time required to fully charge the battery only three hours.

Saito said that the customers will be able to reserve their own WalkCars from autumn 2015 on the crowd-funding website Kickstarter. The futuristic skateboard will have a price-tag of around 100,000 Japanese Yen (approx. $800 USD). Shipping is expected to begin by spring 2016. *** [EKA | FROM VARIOUS SOURCES | DAILY MAIL]

Potatoes are believed to make us smart

Scientists believe that the potato fueled the remarkable development in the evolution of the human brain. The movement towards consumption of meat previously said to be the main cause of this increase. But a new study says it is driven by the consumption of carbohydrates, particularly in the form of starch.

Big complex brains require lots of energy to develop and function properly. While synthesis of glucose from sources other than starch-rich tubers like potatoes is possible, it is not especially efficient, and such high glucose demands would not have been met on a low carbohydrate diet. (Picture from: http://dailym.ai/1hwUvpA)

As reported by the Daily Mail, that starch is available for the population of our ancestors in the form of potatoes, grains, fruits and nuts. The discovery of how to control the fire makes the potatoes can be cooked, while the saliva protein evolution known senagai extra amylase gene makes humans could unravel calorie-rich starches into sugars to feed the brain.

The human brain uses up to 60 per cent of the body's blood glucose. It is thought that cooked starchy food like potatoes could have provided a glucose-rich diet necessary for this to develop in our early ancestors. (Picture from: http://dailym.ai/1hwUvpA)

Dr. Karen Hardy, the lead investigator of Autonomous University of Barcelona, ​​said that the brain uses 60 percent of our blood glucose and it seems not to be fulfilled if we are less intake of carbohydrates.

Extra amylase gene, combined with knowledge of cooking, increase the availability of glucose to the brain rations. That in turn enables the acceleration of brain size that occurred about 800,000 years ago onwards.

"Eating meat may be the beginning of the evolution of the enlargement of the brain, but the cooked food that has sat flour coupled with increasing saliva amylase genes make us more clever," said Dr. Karen in a study published in the journal The Quarterly Review of Biology. *** [EKA | FROM VARIOUS SOURCES | DAILYMAIL]

Funds for the company's development and motorcycle line up were taken from the British government grant that given recently in the amount of £4 million (equivalent Rp.84,2 billion). That kind of money is also used to increase plant facilities and recruit new employees. So we'll wait for further news.

Kept spur your adrenaline on the power of the two-wheeled monster and stay alive with true safety riding. May God will forgive Your sins and so does the cops...... *** [EKA | FROM VARIOUS SOURCES | BIKE SOCIAL]
