Weathervane

A weathervane has four steady arms. Each arm bears a letter telling in which direction in points, E, S, W, or N.

Above the four arms is an arrow that turn about with the wind. When the west wind blows it turns the arrow round so that its point points to the west. When an east wind blows round goes to the east. The "point" of the arrow always points to whatever wind is blowing. If you look at the arms you can tell in what direction the arrow points. If it points somewhere between the north arm and the west arm, a north-west wind is blowing.

Sometimes a weathervane has a cock on it instead of an arrow. It is then called a weathercock. The beak of the cock always points to the wind that is blowing, and we can tell the name of the wind by looking at the arms. If the beak points in the same direction as the N-arm, a north wind is blowing.

Nightsoil men

In Victorian time, building were often put up before water and sewage pipes were laid down so a single tap or pump might have to serve hundreds of people.

In 1858, the Thames in London became so smelly that the year was known as 'the year of the Great Stink'!

Panic or panick

There is only one spelling for panic ; the verb is inflected 'panic, panics, panicked, and panicking’. The form panick is used for progressive tense, past tense and past participle. We don't write panick today, though English speakers from a few hundred years ago might have (in the same way they might have written musick). When the alternate spelling “panick” is used for the past participle: "I panicked last night at the disco." When it’s use for progressive tense: “Invariably, when markets are panicking, they sell the stocks quickly.” It's the rule for root words ending in "c" is that you have to add “k”, so the spelling is related with the pronunciation. If we don't add the <k>, it looks as if the <c> has to be pronounced /s/. If the "k" was not there, “panicing” would look like the word which is supposed to be pronounced as if it is ended in "sing," while “paniced” would be pronounced like “panised”. The same ...

Bidmas, Bedmas, Bodmas, Pedmas And Christmas

This BBC GCSE Bitesize post says, BODMAS stands for 'brackets', 'other', 'division', 'multiplication', 'addition' and 'subtraction'. It's the order in which we carry out a calculation. But another article says, the order of operations in Maths called BIDMAS. BIDMAS stands for Brackets, Indices, Division and Multiplication, Addition and Subtraction. The difference is that the second substitute 'o' with 'i', and we can understand that teacher normally chooses easy way to explain whose pupils can understand, exponent or power or indices are out of reach of foundation students, so teachers uses 'other' instead. And in this article , 'o' actually stands for 'order', as far as my memory can go, my English teacher never teach me 'order' actually means 'Powers and Square Roots, etc.' In United States, the mnemonic fo Order of Operation is PEMDAS, because brackets are called pa...
