A bad workman always blames his tools

“A bad workman always blames his tools” means somebody always blames something for his own incompetence. This is an equivalent proverb for this wise word: “Buruk muka cermin dibelah,” (Ugly face and the mirror is shattered) There are several examples I’ve encountered:

• “A bad programmer always blames his programming tools,” said Ebonk one time when I complain about my code.
• “A bad photographer always blames his tools,” said D. Setiadi to photographers who think that their cameras are the one who make their photos under-exposure or badly composed. There is even another version for this proverb: “Buruk foto, kamera dijual” (Ugly picture and the camera is sold).
• “A bad experimentalist always blames his laboratory equipment,” somebody once said to me concerning laboratory science.

Now what about theoretical physicists? Does a bad theorist always blames his brain?
