The Kazusa System of Well Boring

The system has for long been in use in Japan. The initial outlay is small, the whole apparatus will cost about Ks. 200 to set up and it can, it is stated, be managed by the ordinary Indian villager. The geological formation of the country when Kazusa wells are operated is mostly sand and red clay and the first water-bearing stratum is reached at an average depth of 300 ft., but the boring can b...

Boring algae

and an increased chlorophyll b to chlorophyll a ratio for better light capture in low light. Furthermore, an Ostreobium strain living in a coral skeleton, where nearly all of the red light has been captured by the zooxanthellae in the coral tissue, has been shown to have modified chlorophyll with a spectrum shifted towards far-red wavelengths. As zooxanthellae cannot use far-red light, more of ...

Why Mathematics is Boring

Storytellers have many strategies for luring in their audience and keeping them interested. These include standardized narrative structures, vivid characters, breaking down long stories into episodes, and subtle methods of reminding the readers of facts they may have forgotten. The typical style of writing mathematics systematically avoids these strategies, since the explicit goal is “proving a...

Nothing Boring About Boron.

The trace mineral boron is a micronutrient with diverse and vitally important roles in metabolism that render it necessary for plant, animal, and human health, and as recent research suggests, possibly for the evolution of life on Earth. As the current article shows, boron has been proven to be an important trace mineral because it (1) is essential for the growth and maintenance of bone; (2) gr...
