Astrobiofisikamimetika

Tahukah Anda bahwa arsitektur menara Eiffel terilhami oleh tulang paha, yakni tulang teringan dan terkuat dalam tubuh manusia? Ini hanyalah satu dari sejumlah contoh dalam ilmu pengetahuan dan teknologi yang akan kami paparkan kepada Anda. Di mana pun, setiap makhluk hidup, dari tumbuhan hingga hewan, di daratan dan di lautan, dilengkapi dengan sifat dan ciri yang mengagumkan. Teknologi yang diyakini sebagai buah karya cipta manusia semata ternyata sudah lebih dulu ada di alam. Karya ini bertujuan memaparkan fakta-fakta dan mengingatkan betapa kelirunya manusia yang merasa sombong atas hasil karya mereka.

Lecture 11 - Special and General Relativity (cont.)

 

 

 

Overview:

 

 

The lecture begins with a comprehensive overview of the historical conditions under which Einstein developed his theories. Of particular impact were the urgent need at the turn of the 19th century to synchronize clocks around the world; Einstein's position at a patent office; and a series of experiments that he himself carried out. In 1905 Einstein published three papers that are still considered the greatest papers in the field of physics. The lecture then moves to General Relativity and how it encompasses Newton's laws of gravity. A visual demonstration shows how space-time undergoes curvature when mass is introduced. Class ends with a question-and-answer period on a variety of topics in Special Relativity.

Astrofisika



"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."

~Andrea H.~




 Lecture 10 - Tests of Relativity

 

 

Overview:

 

The lecture begins with the development of post-Newtonian approximations from Newtonian terms. Several problems are worked out in calculating mass, force and energy. A discussion follows about how concepts like mass and velocity are approached differently in Newtonian physics and Relativity. Attention then turns to the discovery that space and time change near the speed of light, and how this realization affected Einstein's theories. Finally, the possibility of traveling faster than the speed of light is addressed, including how physicists might predict from laboratory conditions how this might occur. Muons, unstable particles that form at the top of the Earth’s atmosphere, are used as an example.
