*Fermi's Excellent Adventure*<http://www.symmetrymagazine.org/cms/?pid=1000769>
Since its launch in June 2008, the Fermi Gamma-ray Space Telescope has shed
light on some of the brightest, most explosive events in the universe and
opened tantalizing windows into dark matter and the nature of space-time.

<http://www.symmetrymagazine.org/cms/?pid=1000770> Preserving the Data
Harvest <http://www.symmetrymagazine.org/cms/?pid=1000770>
Canning, pickling, drying, freezing— physicists wish there were an easy way
to preserve their hard-won data so future generations of scientists, armed
with more powerful tools, can put it to good use. They've launched an
international search for solutions.

Chugging along in the background, old physics machines are the workhorses
behind many cutting-edge projects, from the world's most powerful X-ray
laser to the Large Hadron Collider and a lab that tests microchips bound for
Mars.

Other Stories: Editorial: Where the Past Meets the
Future<http://www.symmetrymagazine.org/cms/?pid=1000765>- Particle
physics spends a lot of time concentrating on the past and the
future. That's not a criticism, just a reflection of the long-term nature of
the science. But now is a special moment in the history of particle physics.
Commentary: Deb Wieber
<http://www.symmetrymagazine.org/cms/?pid=1000766>- "Once again we
find ourselves neighbors with Fermilab, even though we
moved almost all the way to Canada! How bizarre is that? The laboratory has
a much bigger impact on our lives than it did 31 years ago." Signal to

What opera and physics may have in common, more than anything else, is their
tendency to make most people cringe or fall asleep. Can an avant garde opera
that compares self-exploration to the physics of multiple dimensions
invigorate audiences? The creators of *Hypermusic Prologue, A Projective
Opera in Seven Planes* think so. Deconstruction: Fermilab
Rap<http://www.symmetrymagazine.org/cms/?pid=1000773>- Steve Rush, aka
funky49, sheds some light on "Particle Business," a
nerdcore rap he wrote about experimenters racing to discover the Higgs boson
at Fermilab's Tevatron Collider. Accelerator Applications: Furniture

accelerators provide clues as to how the universe began, but they also
prevent coffee rings. For about 25 years, companies around the world have
been using beams of electrons from particle accelerators to make scratch-

1947, Stanford Linear Accelerator Project Report No. 7
announced the realization of a dream 15 years in the making: the linear
acceleration of electrons. The report was four words long. Explain it in
60 Seconds: Scintillators
<http://www.symmetrymagazine.org/cms/?pid=1000776>- Scintillators are
transparent materials that allow scientists to detect
particles and other forms of radiation. When radiation hits a scintillator,
the material absorbs some of its energy and makes it visible by emitting a
flash of light.

Untuk yang berminat, bisa berlangganan edisi cetak Symmetry magazine di

http://www.symmetrymagazine.org/cms/?pid=1000004

Langganan tidak dipungut biaya, dan bisa dilanggan dari Indonesia (ada beberapa kenalan saya yang berlangganan di Indonesia).

Majalah serupa lain yang juga tidak memungut biaya berlangganan adalah CERN Courier.

assalamualaikum wr wb

kemarin ketika saya ngobrol2 dengan dosen sya, sya disajikan sebuah maslah, yaitu
dengan menggunakan rangkain infrared detektor buatan sendiri dan bolam lampu dengan elemen lurus???
hubungan variabel apa yg dapat ditemukan????
bagaimana menemukannya???

saya mencoba mencarirangkaian infrared detektor ternyata tidak menggunakan LDR, dan ketika untuk mengukur intensitas bgaimana??
saya tambah pusing?

mohon bantuannya dan terima kasihsebelumnya
