The Best Lead Grade For Every Application

For thousands of years, people have used graphite to exercise creativity and bring ideas to life. Graphite is the key component of modern day pencil lead—in fact, lead is a misnomer as it’s actually made up of a mixture of graphite and clay. The formulation of this mixture determines its lead grade. The higher the proportion of graphite content relative to clay the lead has, the softer and darker the lead will be, and vice versa.

Lead grade is an important consideration for both the artist and writer. The hardness of a lead affects its strength, smoothness, smudge resistance, and pigmentation. Writers can fine tune the darkness of their lines by moving a step up or down in lead hardness, while an artist can employ the full range of lead grades to achieve different effects.

Vertiwalk: An Alternative to Stairs

“Vertical Walking is a new system to move yourself between floors in a building. By exploiting the potential of the human body and materials, only a fraction of effort is required, compared to taking stairs. No external energy is needed.”

The intersection of how making things working for folks that are differently abled due to disease, age or some other issue and how that opens up new ways of looking at things for everyone else is really interesting. In the United States, your lifetime chance of dying from a fall is 1 in 114. The CDC states: “Every second of every day in the United States an older adult falls, making falls the number one cause of injuries and deaths from injury among older Americans, [for a total of 27,000 each year].

Changing the stair paradigm could make our residences much safer. It would also open up new architectural options.

Eliminating Rust

“The story is, Australian sheep farmers noticed that steel things that sheep often rubbed against did not rust. Sheep’s wool is thick with lanolin, which is removed in processing the wool. Soap makers use it, it is also used in cosmetics.

One pound of anhydrous lanolin from eBay costs about $16. I mix it about 10:1 with light oil and apply with a brush or cloth. I also mix it with WD40 in a trigger spray. A pound goes a long way.

Since starting this about 10 years ago, rust is a thing of the past – except where I failed to apply this mixture. It has been 100% effective.”

New Kilogram Standard

“Officially, in the US, 1 pound is defined as 0.45359237 kilograms. A foot is defined as 0.3048 meters…

[As of today, the kilogram is being redefined in terms of Planck’s constant, which we only recently measured accurately enough to derive kilograms from it to an acceptable level of accuracy:]

The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10-34 when expressed in the unit J s, which is equal to kg m2 s -1 , where the meter and the second are defined in terms of c and ∆νCs.

[And this has happened before with the meter:] By 1983, physicists had gotten really good at measuring the speed of light. So they used it to fix the length of the meter forever, to make it permanent. Here’s how: They redefined the meter to be equal to the distance light travels in a vacuum in 1/299,792,458 of a second. Essentially, the definition of the meter is now baked into the definition of the speed of light…”
