The speed of light being a constant sounds like a simple statement. But there is more to it, quite a bit more. Let’s look at what this constancy really means. İlk bakışta, it says that if you are standing somewhere, and there is a ray of light going from your right to left, it has a speed c. And another ray of light going from left to right also has a speed c. So far, so good. Now let’s say you are in a rocket ship, aşağıdaki şekilde gösterildiği gibi, moving from right to left.
Özel Görelilik Teorisi
Einstein ve özel görelilik hakkında duyduğunuzda (ya da özel görelilik kuramı, gerçek adını kullanmak için), ünlü düşünüyorum 
denklem, ve ikiz paradoks gibi garip şeyler. Bu şeylerin doğru ve önemli olmakla birlikte, SR çözmeye çalışır sorunu tamamen farklı bir tanesidir. Fizik temel ilkesini savunmak için bir girişim.

Quantum Mechanics – Interpretations
Whenever we talk about Quantum Mechanics, one of the first questions would be, “What about the cat?” This question, gerçekten, is about the interpretations of Quantum Mechanics. The standard interpretation, Sözde Kopenhag yorumu, leads to the famous Schrodinger’s cat.

Quantum Field Theory
In this post on Quantum Mechanics (QM), we will go a bit beyond it and touch upon Quantum Field Theory – the way it is used in particle physics. In the last couple of posts, I outlined a philosophical introduction to QM, as well as its historical origin – how it came about as an ad-hoc explanation of the blackbody radiation, and a brilliant description of the photoelectric effect.

Historical Origin of Quantum Mechanics
Bu bölümde, we will try to look at the historical origin of Quantum Mechanics, which is usually presented succinctly using scary looking mathematical formulas. The role of mathematics in physics, as Richard Feynman explains (in his lectures on QED given in Auckland, New Zealand in 1979, available on YouTube, but as poor quality recordings) is purely utilitarian.

Kuantum Mekaniği
Kuantum Mekaniği (QM) is the physics of small things. How do they behave and how do they interact with each other? Conspicuously absent from this framework of QM is why. Why small things do what they do is a question QM leaves alone. Ve, if you are to make any headway into this subject, your best bet is to curb your urge to ask why. Nature is what she is. Our job is to understand the rules by which she plays the game of reality, and do our best to make use of those rules to our advantage in experiments and technologies. Ours is not to reason why. Gerçekten.
Classical Physics
The main difficulty in describing particle physics to general public is the fact that it is built on modern physics. Even if you are physics aficionado and did extremely well in your high school physics, what you have learned and loved is classical physics. The difference between classical physics and modern physics is not just more physics, but a completely new way of looking at the reality around us.

indirgemecilik
Tüm bilimsel çabalar, biz şeyleri anlamak ve incelemek için benzer üst düzey teknikleri kullanmak. En yaygın teknik indirgemecilik olduğunu. Bu davranış inancına dayanmaktadır, Büyük ve karmaşık nesnelerin özellikleri ve yapısı onların basit bileşenlerinin bakımından anlaşılabilir. Başka bir deyişle, Biz bütün anlamaya çalışın (the universe, Örneğin) küçük açısından, azaltılmış bileşenler (Bu parçacıklar gibi).
Parçacıklar ve Etkileşimleri
Yeni, Ben Desy bir gezi planladıklarını kızımın sınıf arkadaşları parçacıklar ve etkileşimleri bir konuşma yaptı, Almanya ve tüm hakkında ne bir fikir var istedim. Bu tür benim ilk konuşma olarak, Ben bilmiyordum çünkü ben biraz gergindim hangi seviyede, ve arka plan, Ben de konuşmak peg olmalıdır. Ben çok basit hale istemiyordu, Ben zaman kaybı olacağını düşündüm hangi. Ne de çok teknik yapmak istemiyordu, Ayrıca farklı bir şekilde işe yaramaz hale hangi.
Sensory and Physical Worlds
Animals have different sensory capabilities compared to us humans. Cats, Örneğin, can hear up to 60kHz, while the highest note we have ever heard was about 20kHz. Görünüşe göre, we could hear that high a note only in our childhood. Bu yüzden, if we are trying to pull a fast one on a cat with the best hifi multi-channel, Dolby-whatever recording of a mouse, we will fail pathetically. It won’t be fooled because it lives in a different sensory world, while sharing the same physical world as ours. There is a humongous difference between the sensory and physical worlds.
