Haggis Haggis is a savoury pudding containing sheep's pluck (heart, liver, and lungs); minced with onion, oatmeal, suet, spices, and salt, mixed with stock, and
1 − 2 + 3 − 4 + ⋯ 1 − 2 + 3 − 4 + ⋯ In mathematics, 1 − 2 + 3 − 4 + ··· is the infinite series whose terms are the successive positive integers, given alternating signs. Using sigma summation notation the sum of the first "m" terms of the series can be expressed as The infinite series diverges, meaning that its sequence of partial sums, , does not tend towards any finite limit. Nonetheless, in the mid-18th century, Leonhard Euler wrote what he admitted to be a paradoxical equation: A rigorous explanation of this equation would not arrive until much later. Starting
