Clean your food/drink cans, packaging, boxes
This is information worth sharing
A stock clerk was sent to clean up a storeroom in Maui, Hawaii.
When he got back, he was complaining that the storeroom was really filthy and that he had noticed dried mouse/rat droppings in some areas. A couple of days later, he started to feel like he was coming down with stomach flu, complained of sore joints and headaches, and began to vomit.
He went to bed and never really got up again. Within two days he was severely ill and weak. His blood sugar count was down to 66, and his face and eyeballs were yellow. He was rushed to the emergency at Pali-Momi, where he was diagnosed to be suffering from massive organ failure. He died shortly before midnight.
No one would have made the connection between his job and his death, had it not been for a doctor who specifically asked if he had been in a warehouse or exposed to dried rat/mouse dropping s at any time. They said there is a virus (much like the Hanta virus) that lives in dried rat and mouse droppings.
Once dried, these droppings are like dust and can easily be breathed in or ingested if a person does not wear protective gear or fails to wash face and hands thoroughly.
An autopsy was performed on the clerk to verify the doctor’s suspicions.
This is why it is extremely important to ALWAYS carefully rinse off the tops of canned sodas or foods, and to wipe off pasta packaging, cereal boxes, and so on.
Almost everything you buy in a supermarket was stored in a warehouse at one time or another, and stores themselves often have rodents.
Most of us remember to wash vegetables and fruits but never think of boxes and cans.
The ugly truth is, even the most modern, upper-class, super store has rats and mice. And their warehouse most assuredly does!
Whenever you buy any canned soft drink, please make sure that you wash the top with running water and soap or, if that is not available, drink with a straw. The investigation of soda cans by the Center for Disease Control in Atlanta discovered that the tops of soda cans can be encrusted with dried rat’s urine, which is so toxic it can be lethal. Canned drinks and other foodstuffs are stored in warehouses and containers that are usually infested with rodents, and then they get transported to retail outlets without being properly cleaned.

Calculus for beginners
Historically the credit for inventing calculus goes to Sir Isaac Newton and Gottfried Wilhelm Leibniz. There was some work done in this field by earlier people including, the Indian mathematician, Bhāskara of 12th century.
Calculus can be simply defined as study of change. What change? Any change for example, movement is a change. Movement is change of the position (and shape) of an object with time.
Limit: The following example from Wikipedia nicely illustrates Tangent line as a limit of secant lines. The derivative f′(x) of a curve at a point is the slope of the line tangent to that curve at that point. This slope is determined by considering the limiting value of the slopes of secant lines.
Differentiation: When two (or more) related variables change, how does a change in one variable affects the other variable? What is the change rate at any given point? This change rate is defined as a derivative. And the process of obtaining derivative of a function f(x) with respect x is called differentiation.
Integration: Suppose we have an object that moves at a speed (rate of change of distance) that itself changes with time. What will be the cumulative distance traveled by the object over a period of time? Then we have integration that can answer this question.
Here are some of the useful sites to understand the concepts of calculus.
- General introduction to calculus (Wikipedia)
- Definition of the Derivative includes explanation, with illustrations, of the physical and geometrical concepts of the derivative.
- Calculus on Wikibooks has simple and good online tutorials on calculus.
- For advanced calculus students, MIT open course ware has many calculus courses part of its mathematics courses. All these lessons have online and downloadable versions including videos lessons. These courses cover a spectrum of subjects ranging from single variable calculus to multi-variable partial differential equations to mathematical analysis. and its applications
Does anybody have best ways/tools to teach calculus?
Ganesh Festival 2008 at Mumbai
Ganesh immersion 2008 in Arabian sea at Girgaon Chowpatty beach, Marine Drive, Mumbai.
This is the first movie from my new Sony handycam. Its a cool model with 40x optical zoom! (digital zoom is 2000x). It doesn’t have the hassles of video cassette and DVD..
It has a kewl 30 GB hard disk.
