Hi đ Iâm Simon.
Iâm a chemist with a PhD.
I spent years learning how science actually works.
Now I spend far too much time on the internet watching people confidently explain how it doesnât.
So I write about chemicals, food, agriculture, medicine, AI and evidence.
I make complicated science simple.
I challenge claims that donât survive the evidence.
And I explain what the headlines leave out.
Science is complicated enough.
The internet doesnât need to make it worse.
Welcome.

Your stomach contains hydrochloric acid. Your cells produce hydrogen peroxide. Your body makes formaldehyde.
And youâre worried about chemicals?
You ARE chemicals.
We've reached a strange point in history.
Humanity has never had more access to scientific knowledge.
And yet millions of people are being convinced to fear vaccines, food technology and modern medicine.
The problem isn't a lack of information.
It's a crisis of trust.
Imagine telling a pilot you don't believe in aerodynamics.
Or a structural engineer that gravity is just a theory.
Now imagine telling a chemist that chemicals are dangerous because they have complicated names.
Welcome to my comment section.
In France, Farmers have the lowest overall cancer rates compared with the French populationâŠ
đŽ Cancers en France · Les agriculteurs sont les moins touchĂ©s globalement par rapport Ă la population françaiseâŠ
En 2024, tous cancers confondus, la proportion dâassurĂ©s pris en charge ou sous surveillance pour un cancer Ă©tait infĂ©rieure de 7,1 % au rĂ©gime agricole, par rapport Ă lâensemble des rĂ©gimes dâassurance maladie, Ă Ăąge et sexe comparables.
Ces chiffres viennent de la MSA (Mutualité sociale agricole), la Sécurité sociale du monde agricole. Elle couvre notamment les exploitants, les salariés agricoles et les retraités du régime.

Want to spot bad science instantly?
Ask three questions:
At what dose?
Compared to what?
Whereâs the evidence?
Youâve just made 90% of internet health scares considerably less frightening.
Your stomach contains hydrochloric acid. Your cells produce hydrogen peroxide. Your body makes formaldehyde.
And youâre worried about chemicals?
You ARE chemicals.
Nature invented cyanide.
Nature invented poison ivy.
Nature invented botulinum toxin.
Humans invented the phrase â100% naturalâ as a selling point.
Hi, chemist here.
Yes. But not for the reasons you think.
Designing a synthetic route is one thing.
Actually making the molecule is another.

Itâs time to make X Twitter again.
More curiosity.
More humour.
More science.
More intelligent conversations.
Less outrage.
Less misinformation.
Less manufactured division.
Make people smarter, not angrier.
Whoâs with me?

What does your support for @ACSHorg actually do?
â
$250 exposes useless supplements
â
$100 debunks drug myths
â
$50 confronts chemical scares
Every dollar you give now is DOUBLEDâup to $152,000 thanks to our board.
@adolaskie breaks down the details:
Big Pharma isnât trying to kill you.
Vaccines work.
mRNA is in everything you eat.
Everything is made of chemicals.
Natural is not a synonym for safe.
Itâs the dose that makes the poison.
Most internet health scares donât survive five minutes of basic science.
Itâs time to make X Twitter again.
More curiosity.
More humour.

More intelligent conversations.

Itâs 2026.
And weâre still arguing about whether glyphosate causes cancer.
Whether vaccines cause autism.
Whether mRNA vaccines are dangerous.
Meanwhile, scientists are developing new cancer treatments, preventing diseases, improving agriculture and finding ways to feed billions of people.
Imagine what we could achieve if we spent less time recycling old fears and more time understanding new discoveries.
Science is moving forward. Our public conversations need to catch up.
Yes.

Science taught me to question everything.
Music taught me to listen.
Both taught me that the more you learn, the more you realise how much you donât know.
