EdX onlajn kurs astrofizike sa Australian National University (ANUx ANU-ASTRO1x). Kurs je besplatan, osim za one koji žele sertifikat (što je ukupno 4x50 USD - inkorporira 4 kursa, sve zajedno 180USD.) Prezentatori su astrofizičari profesori Brian Schmidt i Paul Francis. Svi kursevi zajedno su ekvivalent prve godine studija astrofizike na ANU.

ANU Astrophysics Course: Syllabus
The Four Courses
We are offering four courses (ANU-ASTRO1x, ANU-ASTRO2x, ANU-ASTRO3x, ANU-ASTRO4x) which
together make up the ANU’s first year astrophysics course. These courses can be taken in any order. ANU-
ASTRO1x introduces some topics used in the other courses, so if you don’t do it first, you may need to do a
little background reading.
Here is the combined syllabus for these four courses.
ANU-ASTRO1x Greatest Unsolved Mysteries of the Universe
Section 1: The Expanding Universe
Section 2: The Big Bang
Section 3: Dark Energy
Section 4: Giant Black Holes
Section 5: First Light in the Universe
Section 6: Gamma-Ray Bursts
Section 7: Dark Matter
Section 8: Solar System Formation
Section 9: Life in Space
ANU-ASTRO2x Exoplanets
Section 1: Pulsar planets
Section 2: Finding Planets using Reflex Motion
Section 3: More radial velocity planets and transits
Section 4: Recent transit results
Section 5: Gravitational Microlensing
Section 6: Debris Disks
Section 7: Adaptive Optics
Section 8: Direct Imaging
Section 9: Earth-like planets
ANU-ASTRO3x The Violent Universe
Section 1: White dwarf stars
Section 2: Degenerate stars and Quantum Mechanics
Section 3: Dwarf Novae
Section 4: Classical Novae, the Chandrasekhar Limit and Nuclear Physics
Section 5: Thermonuclear Supernovae
Section 6: Core Collapse Supernovae
Section 7: X-ray astronomy and Neutron stars
Section 8: Special Relativity
Section 9: Black Holes
ANU-ASTRO4x Cosmology
Section 1: Space and Time
Section 2: Dynamics and geometry of our universe
Section 3: Inflation
Section 4: Observational Cosmology
Section 5: New observational techniques
Section 6: Dark Energy
Section 7: Acoustic Peaks
Section 8: Entropy
Section 9: The Origin and fate of the universe
Bonus Section: The Future of Astrophysics

 

 

Zanimljivo.

 

Ima tome pa skoro 2 decenije, kada sam se preselio iz vesele Svrbije u Junatjed Setjts i ja tada jos uvek bejase hat da svoja astronomiseckaja saznanja podelim sa vascelim svjatom, koji samo sto nije to cekao, jelte. Tako sam,  u nekom momentu, bice, naleteo, mozebiti bas na ovaj avstralijski onlajn juniverziti (zipa, pricamo o stvarima koje se dogadjaju nekima i lajftajm ejgou, smrc:)) sa uglavnom, i nazalost, astrofizickim kursevima. Mi, biing an astronomer, a ne tamo neki astrofizicar, bejah dvostruko obeshrabren, zbog nepodobnih kurseva koji su nudjeni, a koje bi cak mozda i uspeo da usaglasim sa svojim interesovanjima nekako da se nisu isprecile neumitne finansijske prepreke u vrednostima teske desetina tisuca AUD.

Ondah se presaltah na NYC visu skolu za racunare, mnogo bese jeftinije... Bar sam tako naivno mislio.

 

Iako se danas bavim sasvim devetim poslovima... A ne racunarima i zvezdocatstvom.

 

 

Maj tu sents: Predavanja o egzoplanetma su zanimljiva u neku ruku (mada je polovina navedenih stvari iz teorijske astronomije), jer u moje vreme ona nisu ni postojala, ostala predavanja spadaju u Opstu Astrofiziku, druga godina Matematickog fakulteta, tj. pickin dim.

Andromeda, Unexpected by Marcel Drechsler, Xavier Strottner and Yann Sainty
Galaxies winner and overall winner – A team of amateur astronomers led by Marcel Drechsler, Xavier Strottner and Yann Sainty made a surprising discovery – a huge plasma arc next to the Andromeda galaxy. Scientists are now investigating the newly discovered giant in a transnational collaboration. It could be the largest such structure in the nearby environment in the univers

Like a dream’: successful return of Nasa capsule with asteroid sample hailed

[I*m with the pilots]

Yesterday, after 10 years of research, the International Astronomical Union have named the asteroid 2013 TF19, "Fraser", after Elizabeth Fraser.

Discovered 2013-08-31 by M. Kusiak, M. Żołnowski at Tincana, it does not pose a threat to humankind and will not collide with Earth for millions of years. It can only be viewed using an advance telescope but luckily is available to see on NASA - National Aeronautics and Space Administration's website.

Mesec prelazi preko Sunca, pri čemu ne može da ga u potpunosti zakloni. Vidljivo duž američkog kontinenta i u direktnom NASA prenosu.

Jeste li gledali polarnu svetlost sinoc? Videla se po celoj Srbiji, videh snimke i iz Hrvatske, Bosne i Grcke, a evo i timelapse snimka iz mog komsiluka u Hesenu:

uf, to mi nikako ne bi trebali da vidimo, to ukazuje na prodor radijacije sa sunca kroz magnetno polje zemlje, da li se desila neka solarna oluja?

- ostajemo li danas bez elektronike?

- da li je naglo oslabilo magnetno polje u najavi izmene orjentacije istog

- ili je neka zvezda u blizini postala supernova pa nas je malo oprljila gama radijacija od tog događaja

Baš htedoh da pitam da li je neko video?
