Acidity is often measured on a pH scale. This is because Danish chemist <a href="https://www.sciencehistory.org/education/scientific-biographies/soren-sorensen/">Søren Peter Lauritz Sørensen</a> invented the concept of pH as a convenient method for expressing acidity. Acidic things have a low pH whereas alkaline things have a high pH.</p> Thu, 17 Oct 2024 22:09:08 +0000 Daniela Padres 10119 at /oss /oss/article/critical-thinking-general-science-climate-change/windmills-donald-trumps-mind <hr /> <p><em>This article was first published in <a href="https://montrealgazette.com/opinion/the-right-chemistry-theyre-not-windmills-donald-theyre-wind-turbines">The Montreal Gazette.</a></em></p> <hr /> <p>The mind works in mysterious ways.</p> Fri, 11 Oct 2024 17:27:45 +0000 Joe Schwarcz PhD 10111 at /oss /oss/article/medical-critical-thinking-health-and-nutrition/processing-information-about-processed-meat <p>The International Agency for Research on Cancer (IARC), an arm of the World Health Organization lists processed meats in its “Category 1,” reserved for substances known to cause cancer in humans. There is really nothing all that noteworthy here except for the official classification. Unofficial advice about minimizing processed meat has been dispensed by nutritional scientists for a long time.

I don’t mean biological descendants; rather, some intellectuals see Galileo’s face in the mirror staring back at them. Freed from the shackles of academia (or simply kicked out of their university), they find a lucrative niche for themselves, telling their enraptured fans that, just like Galileo, they have an Earth-shattering theory… and a mysterious “they”<i> </i>don’t want you to know about it.</p> Fri, 27 Sep 2024 05:56:13 +0000 Jonathan Jarry M.Sc. 10096 at /oss /oss/article/critical-thinking-pseudoscience/your-hairdresser-will-heal-you-now <p>My hairdresser brings me to an isolated room.

The Greeks considered pollen to be the food of kings. There is a reference to bee pollen in the Bible. Ancient philosophers such as Hippocrates, Pliny the Elder, and Pythagoras believed in the therapeutic potential of bee pollen. So, it seems only natural that we, in the present day, would take a fascination with bee pollen.</p> Thu, 19 Sep 2024 15:03:05 +0000 Daniela Padres 10083 at /oss /oss/article/critical-thinking-health-and-nutrition/what-does-health-canada-issued-natural-product-number-npn-supplement-mean <p>Prescription drug sales in Canada amount to roughly $50 billion a year.
