Chapin 1912.

Talking about droplets and airborne. To him "airborne" meant long-range as in many kilometers. Droplet could be through the air more than 1 or 2 m. Plus, he said study it more! We have failed to do that.

Quick thread.

12 foot droplets? I guess they shrunk over the years.

Also, ring worm may be through air.
Page 281. Plague. Droplets means through air over distance, but not long-range.

page 295. Droplets detected, Flugge first found them during SPEAKING, LOUD TALKING, COUGHING and SNEEZING. Tiny droplets. Yup.

Note found 2 meters BEHIND the person

So clearly, our "droplet" has morphed from Chapin's droplet. That's weird.
p 296. How much do they travel? Well even Chapin said droplets fill a room. Five to six hours. Interesting.

(He then goes on to wonder if they are infective, same arguments as today ... sigh ... and he didn't have 100 years of studies to help him.)
p 297. ... on the next page Chapin talks about an experiment that found no strep in saliva in air (aerosol, let's call it), so Chapin expresses doubt this is more than minor.
Here is the minor comment:
p 298 - thinks float.

Flu floats. (He calls it a bacteria because viruses had just in 1898 and forward begun to be discovered and characterized).
p 298. Far more value and interest derive from the AIR NEAR THE SICK.
p 302. That Flugge developed the idea that TB spread by droplets, rather than dust (TB bacteria spat out, that would dry out and float around on dust).

But this is interesting, because Flugge knew that this wasn't limited to 2m, but WOULD FILL A ROOM.
p 305. There is then discussion of experiments where guinea pigs were not infected at distance of 1m from a coughing TB patient. (However, my recollection is Flugge found otherwise.)

So, two theories, dust vs droplet. But recall droplet means "stuff spat out and that floats"
Le Fin.

This was something I looked through while looking for something else (Chapin's droplets "makes sense" to him, quote)

And now you see why I say that every time I open a book I find more contradictory nonsense.

More from History

Folks who don't know history just tweet whatever they want.

On Feb 1935, Bose attacked the Nazis as he was angry as Indians were described as Sub-Humans in Mein Kampf. The British arrested Bose in April 1936, because he insulted the Nazis.


The West at this point had a soft spot for the Nazis. France, Great Britain, Netherlands, Poland all gave the Nazi Salute during the 1936 Olympics in Berlin.

Even during the Spanish Civil War (1936 - 1939), the Western powers observed neutrality as the Fascists rose in Spain.

In 1937, Hitler told British Foreign Secretary Lord Halifax that one of his fav movies was ‘The Lives of a Bengal Lancer’. Why?

‘The Lives of a Bengal Lancer’ depicted a handful of "superior race" Brits holding sway over an entire Indian subcontinent (Sub-Humans).

"Shoot Gandhi. If necessary, shoot more Congress Leaders (Nehru & Bose)."

- Hitler to Lord Halifax, Britain's Foreign Secretary

This statement by Hitler in 1937 angered many pro-Leftist leaders of the INC including Bose.

Bose reached London in Jan 1938, and he met many leaders of the British Labour Party including Attlee.

1938 & 1939 were two huge years for the Indian National Congress. As i always say, the 10-year phase from 1938 - 1948 shaped modern India and it began in 1938 Haripura session.
