Over Population Nightmare from 1960s - Star Trek's Mark of Gideon

Topics: Climate Change, Ecology, Economy, Politics, Star Trek

It's rare I do a "twofer." However, in the absence of a Starfleet/"Space Farce" or warp drive, we have to start thinking about how we're going to feed, clothe and employ the yet-to-be-born since we've yet to establish interplanetary colonies, let alone interstellar ones. Our "leaders" won't discuss the coming conundrum, hence I can only assume they've got nothing but slogans, jingoism and empty rhetoric bandied to stoke our fears and keep them in their comfortable seats.

"The world is expected to add another billion people within the next 15 years, bringing the total global population from 7.3 billion in mid-2015 to 8.5 billion in 2030, 9.7 billion in 2050, and 11.2 billion by 2100, according to new estimates from the UN." Source: 5 ways the world will look dramatically different in 2100, Ana Swanson, Washington Post

Current assessments of climate change could overestimate the amount of carbon that plants .... That’s because models of photosynthesis often leave out a poorly-understood limit on the process. Now US researchers have calculated that if its representation is doubled, climate models predict an additional 9 Gigatonnes of carbon will still be in the atmosphere by 2100, instead of being locked away inside plants.

“Photosynthesis is the largest flux of carbon into terrestrial ecosystems, yet there is still uncertainty in our understanding of its physiological and environmental controls,” says Danica Lombardozzi from the US National Centre for Atmospheric Rese.... “Our findings suggest that TPU [triose phosphate utilisation] currently limits photosynthesis, and TPU limitation may become even more limiting to photosynthesis in the future. Yet TPU-limited photosynthesis is … poorly constrained by observations and is therefore not always included in photosynthesis models.”

Plants may absorb less carbon under climate change, Environmental Research Letters, reported on Physics World

Damnatio memoriae...

Posted by Reginald L. Goodwin on December 14, 2018 at 5:30am 0 Comments

Topics: Civics, Existentialism, Humor, Politics

Damnatio memoriae is a modern Latin phrase meaning "condemnation of memory", i.e., that a person is to be excluded from official accounts. There are and have been many routes to damnatio, including the destruction of depictions, the removal of names from inscriptions and documents, and even large-scale rewritings of history.

In Latin, the term damnatio…

The Perfect Fluid...

If collisions between small projectiles -- protons (p), deuterons (d), and helium-3 nuclei (3He) -- and gold nuclei (Au) create tiny hot spots of quark-gluon plasma, the pattern of particles picked up by the detector should retain some 'memory' of each projectile's initial shape. Measurements from the PHENIX experiment match these predictions with very strong correlations between the initial geometry and the final flow patterns.

Peace. As the post title says, (inspired by Rakim's greatest opening lines), this marks somewhat of a return. I have not posted in a long while, so here I am. I hope everyone whom I have not communicated with; are doing well. 

I will be checking in more often than not.

Peace.

The Diversity Track & Black Science Fiction Society Back For Dragoncon 2019

I just got news this week that the Diversity Track will be back for 2019 at DragonCon. I'm excited to be invited back for another groundbreaking event. Everyone associated with the first one this year knocked it out of the park! I could not ask for better volunteers, guests, photographers, moderators and participants.

Assault of the Mainstream

Posted by Turtel Onli on December 6, 2018 at 8:10am 1 Comment

Now that the Mainstream has tried and failed to take the life force outta the growing indie-Black age movement with its "afro-futuristic" blockbuster along with its here today-gone tomorrow great token Hero of Harlem, who among us is really about winning at  this challenge and profiting from the opportunities it presents?

Their best efforts to corner and control the Black Age is my proof that we are actually winning in this war for minds and market shares.....inspite of addictive  brand loyalty...the Black On Black boycott....and culturally based anti-intellectualisms.  I often present on panels.....over the years since 1992....at San Diego,,,,,Wizards.......C2E2.....on the Black Age or diversity....  Usually with a lame unprofessional uninformed person in charge.  Each time some hater stands up to taut how racist the Black Age is and how he of she gets so much more outta Manga/Anime'.

Sort of like all of the Black folks that spent 8 years complaining about…

THE UNDERGROUND BY ROXANNE BLAND

Life as alpha of a werewolf pack is anything but predictable. But even Parker Berenson is surprised by the latest twist: he’s fallen in love with a space alien. Problem is, he suspects Melera, his sexy new flame, might be the serial killer terrorizing Seattle. Or maybe she isn’t. After all, just because she’s an interstellar assassin doesn’t mean she’s guilty.
