physics quantum

Quantum Physics is the science of things so small that the quantum nature of reality has an effect. Quantum means 'discrete amount' or 'portion'. Max Planck discovered in 1900 that you couldn't get smaller than a certain minimum amount of anything. This minimum amount is now called the Planck unit. With this set of principles underlying the most fundamental known description of all physical systems at the subatomic level and provides accurate descriptions for many previously unexplained phenomena also given insight into the workings of many different biological systems. Ultimately, and most importantly, I believe it describes the nature of the universe as being much different then the world we see.Niels Bohr, the father of the orthodox 'Copenhagen Interpretation' of quantum physics once said, "Anyone who is not shocked by quantum theory has not understood it".

For beginners, I suggest you get aquainted with these experiments: Two Slits,

Two Slits
The simplest experiment to demonstrate quantum weirdness involves shining a light through two parallel slits and looking at the screen. It can be shown that a single photon (particle of light) can interfere with itself, as if it travelled through both slits at once.

Atomic Bomb and Hydrogen Bomb

The Science Behind Nuclear Fission & Nuclear Fusion
By Mary Bellis, About.com Guide

The Difference Between Nuclear Fission & Nuclear Fusion
There are two types of atomic explosions that can be facilitated by Uranium-235: fission and fusion. Fission, simply put, is a nuclear reaction in which an atomic nucleus splits into fragments, usually two fragments of comparable mass, emitting 100 million to several hundred million volts of energy. This energy is expelled explosively and violently in the atomic bomb. A fusion reaction is usually started with a fission reaction, but unlike the fission (atomic) bomb, the fusion (hydrogen) bomb derives its power from the fusing of nuclei of various hydrogen isotopes into helium nuclei. This article discusses the A-bomb or atomic bomb.

How To Learn Physics

How to Learn Physics
PANITIA FIZIK, SMK (L) METHODIST, JALAN HANG JEBAT

Many students approach a science course with the idea that they can succeed by memorizing the formulas, so that when a problem is assigned on the homework or an exam, they will be able to plug numbers in to the formula and get a numerical result on their calculator. Wrong! That’s not what learning science is about! There is a big difference between memorizing formulas and understanding concepts. To start with, different formulas may apply in different situations. One equation might represent a definition, which is always true. Another might be a very specific equation for the speed of an object sliding down an inclined plane, which would not be true if the object was a rock drifting down to the bottom of the ocean. If you don’t work to understand physics on a conceptual level, you won’t know which formulas can be used when.

Fizik Air Mata

BANYAK yang boleh berubah dengan hanya satu kerlipan mata. Bahkan, seluruh lapisan permukaan mata anda berubah setiap kali anda mengerlip mata.
Dalam kira-kira suku saat, cecair mata merembes mata. Ia akan menyapu permukaan lalu meninggalkan lapisan baru yang nipis, sementara selebihnya dialirkan. Walaupun sistem ini mungkin kedengaran mudah, secara fizik, ia agak rumit. Saintis kini menggunakan model komputer matematik untuk cuba memahami bagaimana cecair bergerak di dalam mata dan menjadi air mata.

Kereta Terbang Lulus Ujian

NEW YORK - Dengan hanya menekan beberapa butang sebuah kereta mampu berubah menjadi sebuah kapal terbang dalam masa 30 saat, lapor sebuah akhbar semalam.
Ia mampu terbang pada kelajuan 185.07 kilometer sejam dan bergerak sejauh 724 kilometer dengan menggunakan minyak petrol tanpa plumbum biasa.
Kereta terbang pertama dunia itu dipandu uji oleh seorang juruterbang veteran Amerika Syarikat (AS), Phil Meteer.

Proses Kejadian Alam Menurut Pandangan Al-Quran

Proses kejadian alam ini satu persoalan yang menarik sejak dari zaman dahulu hingga ke hari ini. Manusia masih ingin mencari kepastian asal usul kejadian alam ini. Bagaimana proses kejadiannya. Bagaimana alam ini terjadi dan diciptakan. Manusia masih tercari-cari jawapannya. Manusia tidak jemu-jemu dengan segala usaha dan kemahiran yang ada untuk mencari jawapannya. Ahli-ahli sains hari ini dengan teknologi tinggi dan canggih masih terus berusaha untuk mencari rahsia kejadian alam ini.
