Temperature Effect on Resistance

MIT Physics Demo

A light bulb is connected in series with a coil of very fine copper wire and a DC power supply. The voltage is adjusted so that the bulb glows dimly. When the coil is immersed in liquid nitrogen the resistance of the wire decreases causing the current to increase and the bulb to glow brightly.

"Leadership is not magnetic personality that can just as well be a glib tongue. It is not making friends and influencing people that is flattery. Leadership is lifting a person's vision to higher sights, the raising of a person's performance to a higher standard, the building of a personality beyond its normal limitations."

"Jika Hidup ini seumpama rel kereta api dalam eksperimen relativitas, maka pengalaman demi pengalaman yang mengempur kita dari waktu ke waktu adalah cahaya yang melesat-lesat di dalam gerebong di atas rel itu. Relativitasnya berupa seberapa banyak kita dapat mengambil pelajaran dari pengalaman yang melesat-lesat itu, maka analoginya adalah jika pengalaman yang sama dapat menimpa siapa saja, namun sejauh mana dan secepat apa pengalaman itu memberi pelajaran pada seseorang, hasilnya akan berbeda, relatif satu sama lain."
