When writing down electronically and recording the writing, it is best to use a pencil vs. a pen so it provides the opportunity to erase what is being shown. Standards to be established for uniform data entry, otherwise there is a lot more work to be done.

Raw Milk

Many people are lactose intolerant because they do not have enough of the lactate enzyme found in raw milk. Yes it pasteurized milk preserves longer, but is that what is best for the milk and us?

Wool w/ cotton inside

Micro blended clothing. Cotton for comfort and softness, wool to insulate from moisture. See wools use for absorbing oil. Coarse wool absorbs the oil the best and then can be squeezed out really easily.

Ski boot with built in heater and fan

Use the cold ambient temperature (thermal differential) to increase the output of the heater and the fan. Use the fan and heater to dry the boot at night, get it warmed up before the day, and keep it warm during the day. Built actually into the boot vs. external system.

Tecnica boots.

Brinicle

When there’s a big differential between the water temperature (around -1.9C) and the air temperature above the sea ice (below -20C). The warmer sea flows up to the air, freezing into new ice. According to the BBC, “the salt in this newly formed ice is concentrated and pushed into the brine channels. And because it is very cold and salty, it is denser than the water beneath.” This makes it fall down into the water, creating an ice plume that grows into the brinicle.

How much information is there in the world?

  • Looking at both digital memory and analog devices, the researchers calculate that humankind is able to store at least 295 exabytes of information. (Yes, that’s a number with 20 zeroes in it.)
    Put another way, if a single star is a bit of information, that’s a galaxy of information for every person in the world. That’s 315 times the number of grains of sand in the world. But it’s still less than one percent of the information that is stored in all the DNA molecules of a human being.
  • 2002 could be considered the beginning of the digital age, the first year worldwide digital storage capacity overtook total analog capacity. As of 2007, almost 94 percent of our memory is in digital form.
  • In 2007, humankind successfully sent 1.9 zettabytes of information through broadcast technology such as televisions and GPS. That’s equivalent to every person in the world reading 174 newspapers every day.
  • On two-way communications technology, such as cell phones, humankind shared 65 exabytes of information through telecommunications in 2007, the equivalent of every person in the world communicating the contents of six newspapers every day.
  • In 2007, all the general-purpose computers in the world computed 6.4 x 10^18 instructions per second, in the same general order of magnitude as the number of nerve impulses executed by a single human brain. Doing these instructions by hand would take 2,200 times the period since the Big Bang.
  • From 1986 to 2007, the period of time examined in the study, worldwide computing capacity grew 58 percent a year, ten times faster than the United States’ GDP.
