The rival of Takeda Shingen (1521–1573) was Uesugi Kenshin (1530–1578), a legendary Sengoku warlord well-versed in the Chinese military classics and who advocated the "way of the warrior as death". Japanese historian Daisetz Teitaro Suzuki describes Uesugi's beliefs as: "Those who are reluctant to give up their lives and embrace death are not true warriors.... Go to the battlefield firmly confident of victory, and you will come home with no wounds whatever. Engage in combat fully determined to die and you will be alive; wish to survive in the battle and you will surely meet death. When you leave the house determined not to see it again you will come home safely; when you have any thought of returning you will not return. You may not be in the wrong to think that the world is always subject to change, but the warrior must not entertain this way of thinking, for his fate is always determined."

Ah, so.. Uesugi Kenshin

Botany was greatly stimulated by the appearance of the first "modern" text book, Matthias Schleiden's Grundzüge der Wissenschaftlichen Botanik, published in English in 1849 as Principles of Scientific Botany. Schleiden was a microscopist and an early plant anatomist who co-founded the cell theory with Theodor Schwann and Rudolf Virchow and was among the first to grasp the significance of the cell nucleus that had been described by Robert Brown in 1831. In 1855, Adolf Fick formulated Fick's laws that enabled the calculation of the rates of molecular diffusion in biological systems.

A number of vessels visiting the islands were attacked and their crews killed. In 1834, Captain DonSette and his crew were killed. Similarly, in 1845 the schooner Naiad punished a native for stealing with such violence that the natives attacked the ship. Later that year a whaler's boat crew were killed. In 1852 the San Francisco-based ships Glencoe and Sea Nymph were attacked and everyone aboard except for one crew member were killed. The violence was usually attributed as a response to the ill treatment of the natives in response to petty theft, which was a common practice. In 1857, two missionaries successfully settled on Ebon, living among the natives through at least 1870.:3
