I have been brought up to understand that I live in an expanding universe, but now that theory has been popped. According to an article in Sci-News.com the universe is not expanding. Measurements have been made of the brightness of stars throughout the universe and they are not consistent with that which theory would predict if the universe were expanding in the way presumed for many years. If there is no significant expansion then the red shift seen in the light from distant objects must have another cause.
Controversy rages over what shape of plate food should be served on: Square plates are an ‘abomination’ according to a report about MasterChef judge William Sitwell’s view in the Telegraph. Apparently Mr Sitwell is to hold a ‘Square Plate’ amnesty at the Towcester Food Festival on the 7th and 8th of June 2014. He doesn’t plan to destroy them Greek style. He’s going to give them to charity. This means they will still be in circulation and may be re-used. I can’t really stand a round plant pot on a square plate can you?
The square plate issue came to light in the BBC MasterChef competition when Mr Sitwell (a judge by invitation) made it clear he didn’t like a contestant’s food because it was served on a square plate. He is of the opinion that a square plate suggests a chef using one raises presentation above flavour.
I bought a pair of Merrell MOAB boots for £115 (see featured image) from Millets in Derby 40 days ago and this morning I came back from walking my dog, Leo, and found my left sock was wet because those Merrell boots let in water. They were sold to me as waterproof. Every day I walk a minimum of five miles, 1.5 miles in the morning over wet grass when Leo chases a tennis ball, and 3.5 miles in the afternoon when he just walks. I cannot tolerate wet feet on a regular basis. I must have waterproof shoes or boots. Wellingtons are no good for walking a long distance. My last pair of walking shoes split where the upper and sole join on one foot. That was detected by a wet foot too.
This article is in effect an addendum to the post Repairing A Toilet Silent Fill Valve which explains how to access and dismantle such a valve and inspect or change the diaphragm that sits in the valve. That post also explains what is, and is not, silent about a Silent Fill Valve. This is now complemented by the post Replacing A Toilet Fill Valve.
In order to satisfy the requirements of Internet SEO (Search Engine Optimisation) the valve is referred to, in this article, specifically as a Toilet Silent Fill Valve or more generally Silent Fill Valve but its full title is a Silent Fill Toilet Cistern Inlet Valve since it is:
An Inlet Valve.
A Cistern Inlet Valve.
A Toilet Cistern Inlet Valve.
A Silent Fill Toilet Cistern Inlet Valve.
This type of valve is complex and deploys a built-in mechanism which uses the inherent water pressure in the Mains Water to drive the valve from the closed to open position and then from the open to closed position. The mechanism is controlled by a much smaller valve in the form of a stopper covering a pinhole which requires a much smaller effort to operate it than the main valve.
The article endeavours to explain to the reader how the complete valve works so that they understand the order in which physical processes take place and why they follow on from each other as they do. The theory behind the workings of the valve are developed from the basic principles of forces and pressures acting on the individual parts but without the detail of too many mathematical formulae.
A lengthy report from the BBC tells that these drinking vessels may be returning to some pubs frequented by young people in London. They disappeared from pubs around 2001 when the company making them, Ravenhead Glass in St Helens, closed their factory. They are now made in Turkey apparently.
Not everyone is so nostalgic. Some think that the old glass tankard is not so good for the beer as a modern narrow glass. The old ones have a poor open surface to volume ratio, I believe, allowing the bubbles to escape too soon after the pint is pulled. Yes these pubs PULL their pints.
See the video below, from St. Chad’s College Bar, Durham (not in Dalston), which shows how a Real Ale should be dispensed. Unfortunately an ordinary beer glass is being used here, not a Glass Tankard.
