Sequoias endured 500 years of fiery drought, tree rings show

Hard scientific evidence of the MWP from ancient trees.


1000 year old natural remedy kills modern super bugs (MRSA)

Anglo-Saxon remedy kills hospital superbug MRSA


Fascinating. Considering that care is needed to make a version that is effective.  How many other old scientific remedies are there?  And how many were hand waved away as useless?

Faraday, the electric motor, and SIWOTI (someone is wrong on the internet)

Sometimes while researching things, I come across web pages that are just wrong, and usually I ignore them.

Not today.

Farday is well known as the inventor of the electric motor, the man who discovered the link between electricity and magnetism.  These facts are never in dispute.

This web page just leaves him out of the first paragraph of the story, which is about the invention of the electric motor!
The invention of the electric motor 1800-1854
A short history of electric motors - Part 1
Univ.-Prof. Dr.-Ing. Martin Doppelbauer
With the invention of the battery (Allessandro Volta, 1800), the generation of a magnetic field from electric current (Hans Christian Oersted, 1820) and the electromagnet (William Sturgeon, 1825) the foundation for building electric motors was laid.  
This can not be tolerated.  Faraday demonstrated his invention in 1820.

Faraday is the inventor

Faraday is the important person in the story


Now that I blogged about this, I'm sure the problem has been solved.  Duty calls!

Fukushima radiation field of 3.75 Sv/h above Unit 3, March 17 2011

Thursday, 17 March

During the morning Self-Defense Force helicopters drop water four times on the spent-fuel pools of units 3 and 4.[43] They measure radiation field of 3.75 Sv/h above Unit 3.[44] In the afternoon it is reported that the unit 4 spent-fuel pool was filled with water and none of the fuel rods were exposed.[45] 

Official Transcript

And there is a notable point -- 300 feet 2 above Unit 3 in the air there is a dose reading of  375 R per hour.

375 Rem is 3.75 Sievert

An hour in that sort of radiation is almost certain death.

Since radiation levels are subject to the inverse square law, at 150 feet above Building 3 the dose would be  15 Sieverts an hour, deadly, and enough to make anyone sick very quickly.  Which is why the helicopters stayed so high up when dropping water.

Lets convert time to the metric system

Inspired by a topic.

Why not divide the day into 10 metric hours, each hour 100 metric minutes, each minute 100 metric seconds?  That how the metric system works.

Makes everything easier.


It would make everything easier. In fact, the French actually did this.

For some reason it never caught on.
