Nominasi Peraih Nobel

Nomination forms are sent by the Nobel Committee to about 3,000 individuals, usually in September the year before the prizes are awarded. These individuals are often academics working in a relevant area. For the Peace Prize, inquiries are sent to governments, members of international courts, professors and rectors, former Peace Prize laureates and current or former members of the Norwegian Nobel Committee.

The deadline for the return of the nomination forms is 31 January of the year of the award. The Nobel Committee nominates about 300 potential laureates from these forms and additional names. The nominees are not publicly named, nor are they told that they are being considered for the prize. All nomination records for a prize are sealed for 50 years from the awarding of the prize.

Astrobiology and Space Exploration

"Pencarian akan persahabatan di dunia luar sana, akan membutuhkan kesabaran yang panjang bagi umat manusia"

~Arip~

2. The Search for other Earths and Life in the Universe

Stanford University Course

In the Stanford Astrobiology Course, our lectures follow a more or less linear path from the Big Bang all the way to the development of complex life and, finally, space exploration. It is truly amazing how evolutionary principles have operated at the macro, and micro, level ever since the birth of the universe we reside in today.

Physics, research, experimentation, astronomy, extraterrestrial life, planets, asteroids, cosmology, measurements, data, innovation, development, history, science, telescopes, observations, theories, predictions, telescopes, instruments, light, expansion.

Every year Professor Marcy brings new discoveries to his lecture and this year it was 1200 new exoplanets! Read about the Kepler Team’s announcement in the Wall Street Journal or watch their video.
Save the playlist of Professor Marcy’s latest lecture.
The first of 6 parts begins here:

Also listen on Stanford iTunes to Greg Laughlin’s talk on Extrasolar Planets from 2008. With Arbesman Laughlin has tried to predict how soon an Earth-like exoplanet will be found by extrapolating the rate of discovery so far in the search for habitable exoplanets. See the New Scientist, September 21

A syllabus for the Winter, 2010 Astrobiology Course can be downloaded here.

Below you will find a list of recommended resources. If you would like to learn more about the Big Bang, check out these books, videos, and articles.

"There are so many benefits to be derived from space exploration and exploitation; why not take what seems to me the only chance of escaping what is otherwise the sure destruction of all that humanity has struggled to achieve for 50,000 years?"

Relativitas Umum dan Ke Geniusan Einstein

Teori Einstein memiliki implikasi astrofisika yang penting. Teori ini memprediksikan adanya keberadaan daerah lubang hitam yang mana ruang dan waktu terdistorsi sedemikiannya tiada satu pun, bahkan cahaya pun, yang dapat lolos darinya.

Terdapat bukti bahwa lubang hitam bintang dan jenis-jenis lubang hitam lainnya yang lebih besar bertanggungjawab terhadap radiasi kuat yang dipancarkan oleh objek-objek astronomi tertentu, seperti inti galaksi aktif dan miktrokuasar.

Melengkungnya cahaya oleh gravitasi dapat menyebabkan fenomena pelensaan gravitasi. Relativitas umum juga memprediksikan keberadaan gelombang gravitasi. Keberadaan gelombang ini telah diukur secara tidak langsung, dan terdapat pula beberapa usaha yang dilakukan untuk mengukurnya secara langsung.

Selain itu, relativitas umum adalah dasar dari model kosmologis untuk alam semesta yang terus berkembang.

"Leadership is not magnetic personality that can just as well be a glib tongue. It is not making friends and influencing people that is flattery. Leadership is lifting a person's vision to higher sights, the raising of a person's performance to a higher standard, the building of a personality beyond its normal limitations."

"Jika Hidup ini seumpama rel kereta api dalam eksperimen relativitas, maka pengalaman demi pengalaman yang mengempur kita dari waktu ke waktu adalah cahaya yang melesat-lesat di dalam gerebong di atas rel itu. Relativitasnya berupa seberapa banyak kita dapat mengambil pelajaran dari pengalaman yang melesat-lesat itu, maka analoginya adalah jika pengalaman yang sama dapat menimpa siapa saja, namun sejauh mana dan secepat apa pengalaman itu memberi pelajaran pada seseorang, hasilnya akan berbeda, relatif satu sama lain."
