I love my #dslr camera - though phones are amazingly convenient and that means a lot in photography, nothing beats physics and light-gathering.

Quick comparison.

I was standing, looking at this building. There is a window washer 150m away.

There he is. Here, I'm using my phone camera's natural "5x zoom" lens

Lets use the Samsung-marketed "superzoom!" I can.. well... I can see him.

The phone is doing what it can with its tiny sensor and algorithms. But see that bucket? let's pull out my DSLR.

i can read the bucket from 150m away! (Cropped to hide identity)

extreme zoom:

WARNING! Children can fall into bucket and drown.

(important safety information btw).
Photography is such a great hobby, and if using a phone and its capabilities is what gets you into it, great! There are things you can do with phones that are incredible.

But in photography, photons and sensor size matter!

Battling Election Misinformation
Part 2: "The Mandate"

Contrary to media/republican pronouncements, the election of Donald Trump was one of the narrowest (by popular vote, +1.73%) in history, with only 7 elections since 1800 being narrower.

/1Image
In fact, if we look at the margin of victory when we include all eligible voters, Trump wins with 31.3% of the voting population, compared to Harris' 30.2% and 1% going to other candidates. 37.4% did not vote.

If we only include voters, Trump wins 50.03% to 49.97%

/2Image
When we look at the electoral college results, Trump won 58% of available electoral college votes. This would rank his election 41st out of 57 elections since 1800.

🧵Battling Antivax Disinfo🧵
Vaccination did NOT increase cancer deaths.

Here I took the 6 deadliest cancers (all 5 survival rates under 50%) in a highly vaccinated population (25-54), and we can see ZERO evidence of vaccine-related cancer deaths, all the way to May 2024.

/1Image
If i move ages to 55+, we see the same thing, and we are now looking at a lot of deaths from these extremely aggressive cancers, so this isn't some underpowered stuff here. There is NO evidence that deadly cancers have increased due to vaccination.

None.

/2Image
If we take all ages 5+ and look for until May 2024, we see no increase in these highly aggressive cancer deaths, or any cancer deaths.

The Presidential Election
Data Geekery with my interpretations

1) The Country Shifted, but More Didn't.

The final share will be ~ +1.3 to +1.5% for Trump, which is a shift of ~+5.8%.

If America was a room with 65 people in it, only 2 out of the 65 people switched shirts.

/1Image
Note: this math might seem like it doesn't work, but we have to remember to include those that voted 3rd party (1.5%ish) and those that didn't vote (about 35%).

Excluding non-voters who were eligible,
2020: 22/43 D & 20/43 R
2024: 20/42 D & 21/42 R

/2Image
In other words, the great majority of the country didn't switch, but we know there was definitely a nudge towards republican vote.

What does this mean?
The narratives about "America changing" should be very cautious, as 93% of America did not change.

🚨COVID-19 Vaccination saves lives and improves outcomes 🚨

In this UK study of >3 MILLION PEOPLE who vaccinated, the incidence of mental health problems was significantly reduced when a subsequent COVID-19 infection occurred.

/1Image
Looking at the totals who were infected with COVID-19, it is clear that COVID-19 diagnosis was associated with a ROBUST increase in mental health problems after the diagnosis.

/2 Image
This adds to the massive and still growing body of evidence that Covid 19 Vaccination was safe, effective, and extremely important especially considering that after this study, virtually everyone was infetcted with COVID-19.

Yet another study finding differential impacts (mostly with decrease of symptoms) on the mental health of youth comparing prepandemic to pandemic times.

The media far far far less likely to report on these now common findings.

My colleagues and I talked about this at length, that there were many reasons to be cautious about the early "expert predictions" and in fact when good evidence was considered, many so-called evidence based scientists were wrong: dire outcomes on mental health harder to find.
