Spend 20 years studying Chemistry. Collect data. Publish papers. Pass peer review. Earn a PhD. Go online. Get told you're wrong - by an electric screwdriver salesman. That's the internet. Expertise vs confidence. Science isn't broken. Our respect for it is.

The greatest achievement in human history isn’t getting a few satellites into space. It’s feeding 8 billion people every day. The fact that many people find rockets more exciting than agriculture says more about human psychology than human priorities.

Chemist here 👋 Yes. Bleach is a toxic chemical.

Science is not trustworthy because a scientist wears a lab coat, has a PhD, or holds a prestigious position. Science is trustworthy because claims are transparent, testable, and supported by evidence.

The idea that glyphosate “causes cancer” took off after a hazard classification from in 2015, while regulatory agencies concluded it is unlikely to pose a carcinogenic risk at real-world exposure levels. And here we are a decade later, still re-litigating the same selective interpretation. Such a tiresome waste of time.

The world’s most valuable private company wants to put humans on Mars. One of the companies helping farmers feed humanity is worth roughly 50 times less. Think about that for a moment. SpaceX is worth more than $2 trillion. Bayer is worth around $40 billion. Many people see that and conclude: “Investors care more about going to Mars than feeding the world.” But markets don’t measure importance. They measure expectations. SpaceX’s mission is to make humanity multiplanetary. Bayer’s mission is health for all and hunger for none. One is building a future on Mars. The other is helping humanity solve problems here on Earth. And here’s the irony: The reason we can dream about Mars is because previous generations solved hunger, disease, and countless other challenges that once dominated human existence. Food is so abundant that many people have forgotten how extraordinary that achievement is. Rockets inspire us. Full supermarket shelves do not. One captures our imagination. The other makes civilization possible. Where would you invest your money?

Chemophobia is just marketing to sell you fear.

We don’t have an innovation problem. We have an understanding problem. Scientists invent. Engineers build. Then activists, influencers, and politicians convince the public to fear it. The bottleneck isn’t technology. It’s trust.

All chemicals have the potential to be toxic. It's the dose that makes the poison. That's it. That's the tweet.

Wine contains about 120,000 mg/L of ethanol. Recent reports found around 0.12 mg/L of TFA. That’s a difference of roughly 1 million-fold. Yet watch what happens when both are mentioned in the same headline. One triggers panic. The other gets paired with cheese. This isn’t an argument that TFA should be ignored. It’s a reminder that humans are often terrible at judging risk. Ethanol is a Group 1 carcinogen. According to the WHO, alcohol contributes to tens of thousands of cancer deaths across Europe every year. TFA’s health effects are still being studied. But it’s striking that many people will spend hours debating trace contaminants measured in parts per billion while casually consuming a substance whose risks are already well established. Risk perception is not always driven by evidence. Sometimes it’s driven by familiarity. And familiar risks often get a free pass.

I think should be aware of the danger water can present.

“No more data centers.” To an audience served by one. From a device connected to one. Using an AI model running in one.

Quote of the day:

Chemophobia is a business model. If people stop being afraid of “chemicals,” a lot of wellness influencers stop having products to sell. Creating fear is profitable.

Same hazard everywhere. Risk only where exposure exists. Most people still confuse hazard with risk. A bear is dangerous everywhere. That’s the hazard. But the risk of a bear attack only exists where bears and humans actually meet. That’s exposure.

Notice that chemophobia rarely comes from chemists? The people who spend their careers studying molecules, toxicology, exposure, and risk tend to be the least afraid of “chemicals.” Why do you think that is?
