Selecting the right differential for your rearend build is an important decision that will be with you for a very long time - if you get it right.

Below are short, not-too-technical, overviews of some of the most frequently asked about differential options for Hot Rods, Muscle Cars, and Muscle Trucks. //

Detroit Truetrac - Helical-gear limited-slip (worm differential) is the modern replacement for the classic clutch-type posi. //

Trac-Lok/Posi-Trac – Clutch-type limited-slip (Posi), offered as original equipment in many GM and Ford performance cars, these units rely on clutches (friction plates) to transfer power to the wheels. //

Detroit Locker - Automatic "ratcheting-style" differential is known for its reliability, rugged construction, and fully-locked performance on any surface. When power (torque) is applied in either forward or reverse directions, the unit locks both axles together like a spool. When coasting or rolling through a corner (no torque applied), the unequal speed of the inside and outside wheels causes the unit to unlock momentarily, before abruptly locking when power is applied.

What role did religion play in Johnson’s life? Boswell tried to present him as a High Anglican Tory and Christians today of a conservative inclination today see Johnson as an antidote to what they consider to be the optimistic rationalism of some enlightenment thinking. //

Nicholas Hudson, in his book Samuel Johnson and Eighteenth Century Thought, sums this up:

Few writers were so knowledgeable or sociable to combine many sides of contemporary thought into an understanding of life distinctive for its humanity and good sense. His learning and complexity make his writings especially useful as the starting point for a broader investigation of eighteenth century thought. [18]

And that's as close as you're going to get an active astronaut to saying that what some people call the Deep State is actually where the heroes that keep everything from falling apart work.

What actually makes you a "steely-eyed missile man" isn't bravery, mojo, having XY chromosomes or white skin, it's to

sit in their cubicle for decades studying their systems, and knowing their systems front and back. And when there is no time to assess a situation and go and talk to people and ask, 'What do you think?' they know their system so well they come up with a plan on the fly

Boswell first confronts Johnson with Hume’s ideas in late July 1763, just a few months after his first meeting with Johnson. He spoke of the Politician and agriculturalist George Dempster whose principles had been poisoned by a ‘noted infidel writer’ that is, Hume.

Johnson’s response was that

Hume and other sceptical innovators are vain men and will gratify themselves at any expense. Truth will not afford sufficient food to their vanity; so they have betaken themselves to error. Truth is a cow which will yield such people no more milk and so they are gone to milk the bull.[4]

But what Johnson went on to say is also important:

Everything which Hume has advanced against Christianity had passed through my mind long before he wrote. Always remember this, that after a system is well settled upon positive evidence, a few partial objections ought not to shake it. The human mind is so limited that it cannot take in all the parts of a subject, so there may be objections raised against any thing [5].

"Hey, this is a very precarious situation we're in." //

As it flew up toward the International Space Station last summer, the Starliner spacecraft lost four thrusters. A NASA astronaut, Butch Wilmore, had to take manual control of the vehicle. But as Starliner's thrusters failed, Wilmore lost the ability to move the spacecraft in the direction he wanted to go. //

Wilmore added that he felt pretty confident, in the aftermath of docking to the space station, that Starliner probably would not be their ride home.

Wilmore: "I was thinking, we might not come home in the spacecraft. We might not. And one of the first phone calls I made was to Vincent LaCourt, the ISS flight director, who was one of the ones that made the call about waiving the flight rule. I said, 'OK, what about this spacecraft, is it our safe haven?'"

It was unlikely to happen, but if some catastrophic space station emergency occurred while Wilmore and Williams were in orbit, what were they supposed to do? Should they retreat to Starliner for an emergency departure, or cram into one of the other vehicles on station, for which they did not have seats or spacesuits? LaCourt said they should use Starliner as a safe haven for the time being. Therein followed a long series of meetings and discussions about Starliner's suitability for flying crew back to Earth. Publicly, NASA and Boeing expressed confidence in Starliner's safe return with crew. But Williams and Wilmore, who had just made that harrowing ride, felt differently.

Wilmore: "I was very skeptical, just because of what we'd experienced. I just didn't see that we could make it. I was hopeful that we could, but it would've been really tough to get there, to where we could say, 'Yeah, we can come back.'"

So they did not.
