The universe is shaped like a yarmulke

Apparently, the space-time continuum of the universe can be visualized as a giant yarmulke, from book Steinmetz, Charles Proteus. (1923). Four Lectures on Relativity and Space (First ed). New York, New York: McGraw-Hill Book Company.

Figure 34: Two-Dimensional Analogue of the Universe:

and the footnote on p. 120:

Usually, physicists use the metaphor of a trampoline or a foam mattress to help people visualize the space time continuum, from the PBS NOVA (funded by the people Democrats consider evil: the Koch brothers!) documentary "The Elegant Universe" hosted by Brian Greene:

Not certain I agree with the Steinmetz's glib paraphrase of physics, p. 119:

"The relativity theory has reconfirmed the law of the conservation of energy, but has denied the law of conservation of matter by showing matter as kinetic energy"

People at the University of Colorado seem to share my ambivalence of Dr. Steinmetz's dubious paraphrase in their tutorial on "Mass and Energy Conservation in Nuclear Decay"

Encyclopedia Britannica further clarifies in their article "Principles of physical science :CONSERVATION OF MASS-ENERGY" by Sir A. Brian Pippard:

"Neither of two separate conservation laws, that of energy and that of mass (the latter particularly the outcome of countless experiments involving chemical change), is in this view perfectly true, but together they constitute a single conservation law, which may be expressed in two equivalent ways—conservation of mass, if to the total energy E is ascribed mass E/c2, or conservation of energy, if to each mass m is ascribed energy mc2."

Steinmetz seems to preemptively exonerate himself in his introduction for any and all scientific and mathematical inaccuracies on page V:

Not to be rude to Dr. Steinmetz, but this hand waving seems something of a cop out.

Focusing on the aesthetics versus mathematics of Steinmetz's book, a number of the stereoscopic figures:

Such as Figure 22: Bent Euclidean Two-space:

Figure23: Elliptic Two-space:

Especially Figure 23, reminded me of Paul Klee paintings like his Twittering Machine:

Dyslexic Catholics

FYI, for Catholics who only visit church once a year during Christmas, the proper way to make the sign of the cross:

You're supposed to make the sign of the cross with your right hand, not your left hand, as the guy in the checkered shirt does here:

Physics behind airplanes vs rockets

Fr. Cedric makes common mistake of conflating physics behind airplane motion, i.e. Bernoulli's equation, with that of rockets, i.e. Newton's 2nd law of Motion:


Rocket propulsion uses Newton's 2nd Law of Motion: Law of Conservation of Linear Momentum, and thus can operate in the vacuum of space. From a standard introduction to physics text:  Serway, Raymond A., Robert J. Beichner, and John W. Jewett, Jr. Physics For Scientists and Engineers. Fifth ed. New York: Saunders College, 2000. 

Conversely, aeroplanes operate under Bernoulli's principle and require the presence of a fluid, as scientists would say, or air, as common folks would, and thus planes can't fly in the vacuum of space:

Additionally, whilst on physics, the moon is neither a planet nor a star but is a natural satellite. Even Dish Nation goofs on the lack of scientific knowledge of their home shopping network compadres:

Obama vs #BandOfBrothers Dick Winters leadership styles

Obama still advocates leading from behind:

Conversely, the PBS documentary about Bronze Star winning "Band of Brothers" protagonist Richard Winters "Hang Tough" points out Winters advocated leading from the front :


Narrator (Damian Lewis): Dick Winters lead his soldiers in some of the fiercest battles of World War II. He didn't lead them from the back; he led from the front. His concern lay not only in the mission, but also the well being of his men.

Hence, Dick Winters leadership style and methods diametrically opposed to the feckless current Commander in Chief who cavalierly allows US combat deaths to skyrocket on his watch, as Doug Book pointed out in his October 18, 2012  "Western Journalism" article "Rules of Engagement getting Our soldiers killed at alarming rate"

"Introduced  into the Afghan theater of operations by General David Petraeus in July of 2010, COIN includes 24 'points' to US commanders in the field, all based on the belief that 'alienating Afghan civilians sows the seeds of our defeat.' In short, the intent of COIN is to 'win the hearts and minds of the Afghan people.'

But the winning of those hearts and minds has come at a steep price. During the first 9 years of the war in Afghanistan, 1000 American soldiers were killed. In the 27 months since the adoption of COIN, another 1000 American soldiers have been killed. As a function of time, that’s more than a 400% increase in the number of American casualties."
and reinforced in Allen West's February 13, 2014 post "US military deaths in Afghanistan skyrocket under Obama"

"In the first seven-plus years of war in Afghanistan (October 2001 – December 2008) we lost 630 U.S. soldiers. In early 2009, the Obama administration authorized the implementation of the COIN (Counter-Insurgent) strategy, more focused on 'winning hearts and minds' than winning a war, and over the next five years, the U.S. death toll nearly tripled."

If Pete Carroll had read up on football vs blaming Jews for 911 he might've won the #SuperBowl

As a Steelers fan, I rooted for the AFC team in the Super Bowl so that the Steelers would be in the strongest Conference.

Regardless, I would've rooted against Seattle Seahawks because their coach is an evil 911 Truther:


"'In particular, Carroll wanted to know whether the attack on the Pentagon had really happened. Chiarelli–who was the top-ranking Army official inside the Pentagon when American Airlines Flight 77 crashed into its western side–explained that it had. He said he had lost many colleagues. But Carroll didn’t stop there. He ran through the whole 9/11 truther litany.

' Every 9/11 conspiracy theory you can think of, Pete asked about,' said Riki Ellison, the former NFL linebacker who now runs the Missile Defense Advocacy Alliance and introduced Carroll to Chiarelli. Ellison, along with Seahawks offensive line coach Pat Ruel, was at the meeting as well. 'And he didn’t stop at 9/11–he had lots of questions about the role of the military today.'" 
Ironically, if Pete Carroll had spent more time reading up on football versus coming up with conspiracy theories blaming the Jews for 911, he might have noticed an old article pointing out the risk of interception during big championship games. Mwa ha ha!!!!!

Not a good idea to smoke cigarettes on a rocket launch pad

It's usually inadvisable to smoke cigarettes whilst loading rocket fuel on a launch pad, from Perry Mason "The Case of the Misguided Missile"


it's also a bad idea to drink liquor whilst on duty:

Happy Belated #NationalHatDay

I missed National Hat Day which was January 15 :-(

Women don't seem to wear hats as much as they used to, I blame Vatican II.

From Perry Mason "The Case of the Duplicate Daughter"


Daniel Boone's wife, Patricia Blair, wore a funky hat in "The Case of the Badgered Brother"


Fancy people have fancy hats in "The Case of the Torrid Tapestry "


and poor, downtrodden people have poor downtrodden hats:


The Art of Manliness blog lamented the loss of men's hats on their March 1, 2008 post "Bringing Back the Hat" Not certain if it's fair to blame Vatican II for men not wearing hats, but I don't care about fairness and will blame VII anyway.
