This day in science history: Leonardo da Vinci’s “helicopter”


January 14, 1493

Leonardo da Vinci is remembered as one of history’s most extraordinary artists and scientists. He even created that painting of a woman who almost smiled (it was hundreds of years until someone completely smiled in any work of art).

But his most misunderstood invention might be the “helicopter” he created.

Thanks to the journals of patron Lorenzo de Midici, we know the device’s true purpose.

Today, I took counsel with Leonardo, who showed me a proposal for a new creation that has sprung forth from his fertile mind. I have transcribed our discussion of it.

Midici: What wonder have you presented to me today, Leonardo?

Leonardo: My dear Lorenzo, it is the perfect spinner for pizza dough. You put the dough on the top and spin the base. The angle is perfection.

Midici: You’re joking.

Leonardo: No, my lord, the spinner creates a perfect thickness and circle for the dough.

Midici: Uh, I’m paying you for this? This is such a stereotypical Italian joke. This is like a joke the Flemish would make. You know how I feel about Flemland.

Leonardo: Uh, I was just kidding. I don’t love delicious pizza.

Midici: I’m not saying pizza’s bad, I’m saying that I fund your lavish lifestyle and I want something super cool. Just give me something war-like, and not offensive to Italians.

Leonardo: Fine. This pizza spinner doesn’t carry dough in the air.

Midici: What does it carry?

Leonardo: Steak?

Midici: I think you should go…

Leonardo: People! It carries people!

Midici: Amazing! I’m going to write this word for word in my journal now.

Leonardo’s helicopter never did fly, but years later, it inspired the Teenage Mutant Ninja Turtles’ favorite food: the pizza that Leonardo longed to create.

Thoughts Caused By Imminent Extinction.


A vague 3am thought which has been bugging me.

With the combined efforts of a changing climate, evolving virii and bacteria, increasingly possible nuclear war and the poisoning of our environment for short-term benefits and shorter term bottom lines, extinction of the human species is, at least, a possibility. Oh, and never forget the chance of a stray asteroid impacting on our planet.

At the same time our ever-present human curiosity continues to look for life beyond this planet. There are growing signs that there may well be extra-terrestrial life and proof is being actively sought.

Since homo sapiens first thought of the possibility of life on other planets there has been an assumption that it will be intelligent life. Possibly friendly, possibly hostile.

But intelligent. Evolved from single cells into intelligent beings.

Yet must this be so?

We, as a species, have evolved from earlier species which have not developed intelligence to the level of creating science. Evolution has created many lines of specieal existence, yet only one with ‘human’ intelligence. An attribute which seems to be counter-productive to all other living beings.

Should our intelligent species become extinct, is there any guarantee that another species, of whatever lineage, would develop the intelligence to continue the progress of earthly life to the stars?

There is a distinct possibility that star-gazing, star-reaching intelligence may be a one off, not only on this planet, but also on all planets throughout the Universe.

After COVID-19


I have been noting the excellent coverage by the ABC of the current COVID-19 pandemic. It has been comprehensive and, with the help of Dr Norman Swan, understandable.

There is one area in which it can be improved.

Yes, we need to know ‘new cases’.  Sadly, their continued use of the term ‘total infected’ is a misnomer because some have recovered and are now, theoretically ‘immune’.

The ABC could improve and add a column to their COVID-19 statistics.  We need to know how many have recovered! They are the herd who will protect us with Herd Immunity.

They are also the cohort which would make a very good source for nurses, carers, hospital cleaners, meals-on-wheels people and other front-line workers.

No longer able to be infected, sensible use of sanitising would allow them to do many of the tasks for which non-immune people require so much protection.

Obviously not all recovered COVID-19 patients would be interested in doing caring work but a reasonable percentage will be and they should be fast-tracked into those very necessary roles.

In this time of crisis, we need to use every resource at our disposal to lift our nation back to some form of normality.
