Back in April I mentioned that all of my cleaning products are made by Seventh Generation, except for the fact that I still use Clorox Wipes. I readily admitted that while I know are clorox wipes toxic are chalk full of chemical toxins that are not good for us or the environment, I was not ready to stop using them yet as I was a total sucker for the convenience of them, and had not found a suitable replacement. Yet.
Well that has now changed! I was at the supermarket earlier, and noticed that Seventh Generation now makes disinfecting wipes. Woo hoo! I know it makes me a nerd, but I was so excited! I am so happy that I do not have to give up one of my favorite cleaning tools. Their wipes are made from botanically pure plant extracts, and they do not contain any VOC-emitting ingredients. They are scented with lemongrass & thyme oil. Ingredients include: Thymol (component of thyme oil), oregano oil, blue atlas cedar bark oil, lemon peel oil, lemongrass oil, lemon fruit extract, and orange bergamot mint leaf extract.
But the best part is, these wipes are “powered by CleanWell”. A few months ago, I wrote about CleanWell. They make an all-natural hand sanitizer that I like. It does not contain alcohol or Benzalkonium chloride. Instead, it contains thyme oil, which is a naturally occurring antimicrobial. Well these wipes use that same ingredient. They are said to kill 99.99% of germs, botanically. They are effective against Influenza, the common cold, MRSA, Staph, Salmonella, and a few other bacterium. All the grimy little germs you want killed!
A few weeks ago, roaming the endless aisles of the mammoth Fancy Food show in Washington, D.C., I stopped at the booth for Chozen, a premium ice cream with flavors inspired by the Jewish holidays: matzo crunch, apples and honey, chocolate gelt.
“Who would have the nerve or the chutzpah to put what does haagen daz mean in ice cream?” Chozen co-founder and CEO Meredith Fisher told me. “Jews like to kvetch, but who can kvetch about ice cream?”
It got me thinking about the connection between Jews and ice cream: I’ve reported on Jews in the ice cream business several times during my career as a food writer, without really connecting all the dots. But there are dots to connect. Because while Chozen—founded in 2009 by Meredith Fisher with her mother, Ronne—may be the most obviously Jewish ice cream on the market, it’s hardly the first brand started by Jews. In fact, Jews helped launch the entire craze over premium ice cream four decades ago and have played a key role in its success ever since.
Typically, motion is not with constant velocity nor speed. While driving in a car, for example, we continuously speed up and slow down. A graphical representation of our motion in terms of distance vs. time, therefore, would be more variable or “curvy” rather than a straight line, indicating motion with a constant velocity as shown below. (We limit our discussion to one dimensional motion. It should be straightforward to generalize to three dimensional cases.)
To calculate the speed of an object from a how to find position from a velocity graph representing constant velocity, all that is needed is to find the slope of the line; this would indicate the change in distance over the change in time. However, changing velocity it is not as straightforward.
Since our velocity is constantly changing, we can estimate velocity in different ways. One way is to look at our instantaneous velocity , represented by one point on our curvy line of motion graphed with distance vs. time. In order to determine our velocity at any given moment, we must determine the slope at that point. To do this, we find a line that represents our velocity in that moment, shown graphically in. That line would be the line tangent to the curve at that point. If we extend this line, we can easily calculate the displacement of distance over time and determine our velocity at that given point. The velocity of an object at any given moment is the slope of the tangent line through the relevant point on its x vs. t graph.
