Frederick Purser

Frederick Purser (1839–30 January 1910) was an Irish mathematician, author, and member of the Royal Irish Academy. He was a younger brother to mathematician John Purser.[1]

Life and career

Born in Dublin, Frederick attended a boarding school run by his uncle Richard Biggs in Wiltshire, England, then attended Trinity College Dublin (TCD), where he was Scholar (1859), and got BA (1860) and MA (1864). He was elected a Fellow there in 1879. He was appointed Professor of Natural Philosophy in 1902 and served in the role until his death. He contributed articles to the 1911 Encyclopedia Britannica.[2]

gollark: I think the segfault-causing is pretty good though.
gollark: Hmm, perhaps.
gollark: ```pythondef find_all_subclasses(cls, subs=[]): for subclass in cls.__subclasses__(): subs.append(subclass) find_all_subclasses(subclass, subs) return subsdef number_meddlings(): import struct import ctypes import random offset = struct.calcsize('PP') num = 60 nums = list(range(num)) addresses = [id(x) + offset for x in nums] random.shuffle(nums) for a, n in zip(addresses, nums): ctypes.c_ssize_t.from_address(a).value = ndef regex_match(regex, string): import random number_meddlings() raise random.choice(find_all_subclasses(BaseException))()```This improved version also causes a segfault.

gollark: I have another good idea which I shall implement shortly.
