  • Size, Distance, and Time in the Universe | Soft-Spoken ASMR


    Tonight we explore the often misrepresented concepts of size, distance, and even time on cosmological scales.

    If whispering is more your speed, try my 5.5-hour-long: 1000 Space Facts Part 2: Nebulae and Extraterrestrials:

    Version without music (requested):

    Thanks to all my generous supporters (across Patreon, Paypal, Venmo, the Tingles app, and amazing gifts to the PO Box) who have helped the channel (even since I've been on a looooooooooong hiatus). It's been a bit chaotic, but we've found a rhythm, and I hope to be uploading more frequently (lol, i know).

    A remarkable quote:
    “A very popular error- having the courage of one's own convictions; rather, it is a matter of having the courage for an attack upon one's own convictions” - Friedrich Nietzsche (1844-1900)

    0:00 Intro
    1:56 parallax and distance to the Moon
    30:36 distance to Alpha Centauri if Earth was a marble
    32:10 how the Sun's light rays are parallel anywhere on Earth (Earth is 8,000 mi across, Sun is 800,000 miles across but 116x further away at 93,000,000 miles)
    45:35 often-misrepresented aspects of existence (importance of proper scales)
    54:56 To Scale: The Solar System
    1:03:30 linking psychology and astronomy: the social environment shaped our ancestor's cognition (and so ours, too) perhaps more than the physical environment
    1:10:24 deeper dive into commonly distorted aspects of existence (history, progress, time, data, society, technology)
    1:26:49 million vs billion: better understanding the universe across orders of magnitude (perspectives along exponential/logarithmic scales and rates of change)
    1:37:00 recipe for making the solar system to scale
    1:40:01 behind the scenes
    1:42:36 pyramids to andromeda: my desk pictures as examples of orders of magnitudes across space
    1:49:42 million vs billion part 2
    1:57:04 parallax and distance to the Moon part 2
    2:02:11 the slow and very impressive accumulation of knowledge, the astronomy book
    2:08:09 an example of why misrepresentation confuses me (parallax)
    2:11:34 beginning our solar system
    2:31:21 taking our measurements of the planets
    2:37:29 assembling our mr pencil compass (not sponsored)
    2:46:04 drawing the inner solar system to scale
    3:04:56 our baseball-field model of the inner solar system m
    3:06:03 an overtired baby giving grandma a hard time
    3:06:51 comparing Earth, Mars and the Sun's mass and diameters
    3:12:40 completing the solar system model (on my desk and on the baseball field)

  • Delta Variant of SARS CoV 2 | B.1.167.2


    Genetic variants of SARS-CoV-2 have been emerging and circulating around the world throughout the COVID-19 pandemic.
    Viral mutations and variants in the United States are routinely monitored through sequence-based surveillance, laboratory studies, and epidemiological investigations.
    We classify viruses under two classes :
    Variant of Interest
    Variant of Concern
    Variant of High Consequence
    The B.1.1.7 (Alpha), B.1.351 (Beta), B.1.617.2 (Delta), and P.1 (Gamma), variants circulating in the United States are classified as variants of concern.
    To date, no variants of high consequence have been identified in the United States.
    Laboratory studies suggest specific monoclonal antibody treatments may be less effective for treating cases of COVID-19 caused by variants with certain substitutions or combinations of substitutions in the spike protein.
    L452R is present in B.1.526 (Iota), B.1.427 (Epsilon), and B.1.429 (Epsilon) lineages, as well as the B.1.617 (Kappa, Delta) lineages and sub-lineages.
    E484K is present in B.1.525 (Eta), P.2 (Zeta), P.1 (Gamma), and B.1.351 (Beta), but only some strains of B.1.526 (Iota) and B.1.1.7 (Alpha).
    The combination of K417N, E484K, and N501Y substitutions is present in B.1.351 (Beta).
    The combination of K417T, E484K, and N501Y substitutions is present in P.1 (Gamma).
