How many beans make five?

6.25

Caveat: the above answer is only a ballpark statistical assumption.

In many jurisdictions there are statutory requirements relating to the sale of goods.  Of relevance to this discussion are the laws regarding 'fitness for use'.  Regulations covering the sale of seeds commonly require a germination rate of at least 80% under some set of standard conditions.

80% of 6.25 seeds produces how many bean plants?  You do the maths.

Of course, there are many varieties of beans.  Then there are various climatic conditions, soil types, fertilizers etc.  Now factor in the chances of fungal rot, insect and bird predation etc.
Reading The Cryosphere

A picture is worth a thousand words - but only if you can speak the language.

When examining satellite images of the cryosphere it helps to know something of the mechanisms which can create the effects seen.  The skills needed in interpreting these images can be developed by looking at Google Earth or Wikimapia images without any annotations.  Check the history of an area and then go relic hunting.  Alternatively, look at some satellite images, find something odd and then try to guess what it is.  In general, form follows function.  For example, banks of earth in grids or rings not known to be prehistoric indicate that a site was probably once connected with pyrotechnic activities.
How The Media Has Hurt The Japanese People


First and foremost I have a personal message for the 180 or so heroes who have been working in shifts around the clock to save their nation from a worse disaster than the one that Japan has already suffered.


To the Heroes of Fukushima: 

May you each be most correctly and sincerely honored - not just by by your own nation, but by the whole world.  You have risked your lives to save others.  You are morally remarkable people who have actively taken part in serving our global society.  Through your diligence and perseverance you have become public role models.  You each deserve at least these three medals of honor:
Some Thoughts On Priorities

It occurs to me that in this modern age of demands for instant satisfaction of our wants and needs, the instructions to supervisors of refineries, explosives factories and nuclear power facilities need to be revised.

In order to satisfy the wants and needs of the greatest number of people in the shortest possible time, I propose the following order of priorities:

Instructions To Site Managers In The Event Of Emergency:
Open Thread #1


I have started this blog entry under 'random thoughts' for the benefit of those of my readers who may with to discuss a broader spectrum of my topics than is usual in scientific discussions.

Please stick to 'the Chatter Box' topics unless you are a writer here.

Please note that 'a broader spectrum' does not include the theory that Homer Simpson shot JFK or that advertisements for Ugg boots have a rightful place in science blogs!
Japan Earthquake Increases Flood Risk In Fukushima


During the 2011 Tohoku Earthquake in Japan, the ground level sank along the coast near Onahama Port,  Fukushima Prefecture. This has caused recent average tide levels to rise by about 40cm.

A tide level recording from Onahama Port shows the tide level fluctuations at the time of the quake and the subsquent increase in tide levels.
