沒有烤箱，沒有麵包機，來試試「電気パン」
電気パン 號稱是二次世界大戰后的重大發明，陪日本人度過了一段黑暗的日子。原理很簡單，效果卻很不賴。這樣的歷史，日本人還把它寫進課本當教材教。

[RD][Optics] 造鏡者公式 Lensmaker's equation
![\frac{1}{f} = (n-1) \left[ \frac{1}{R_1} - \frac{1}{R_2} + \frac{(n-1)d}{n R_1 R_2} \right],](https://imageproxy.pixnet.cc/imgproxy?url=https://upload.wikimedia.org/math/d/5/d/d5d9b5b95cf3fd9ea7f2549ae4ee8fa6.png)

where
is the focal length of the lens,
is the refractive index of the lens material,
is the radius of curvature (with sign, see below) of the lens surface closest to the light source,
is the radius of curvature of the lens surface farthest from the light source, and
is the thickness of the lens (the distance along the lens axis between the two surface vertices).
The focal length f is positive for converging lenses, and negative for diverging lenses. The reciprocal of the focal length, 1/f, is the optical power of the lens. If the focal length is in metres, this gives the optical power in dioptres (inverse metres).
