Modeling Urban Growth Shows That Cities Develop in Ways Similar to Cancerous Tumors

A team of environmental engineers and city planners from University College London, the University of Sydney, and École Polytechnique Fédérale de Lausanne has discovered that cities grow in ways similar to the development of cancerous tumors. In their paper published in Journal of the Royal Society Interface, the group used mathematical models to explain how the city of London grew into its current state, and then applied the models to Sydney, Australia.

Prior research has shown that most modern cities began as small towns and grew over time to become much larger. In this new effort, the researchers wanted to learn more about the ways that cities grow and why they grow as they do. To that end, they used a number of mathematical models to describe how the city of London grew from a small town into a major city.

They found that London started as a small town, just a square mile in size. That size, they found, suited the people that lived there, as it allowed them to visit all parts of the town with the types of transportation available at the time—namely, walking and going on horseback. But with the arrival of train transport, people in the city began moving to its edge, hoping for a less crowded environment. And that led to more growth.

As time passed, roads allowed people to drive cars and trucks in and out of the cities, spurring even more growth and furthering the spread of the city. The researchers refer to such growth as being similar to angiogenesis, which is the process by which new blood vessels form in living creatures. They further describe such growth as similar to the way cancerous tumors grow.

To find out if other cities grow in the same ways, they applied their model to Sydney and found it was remarkably similar. They conclude that their model could be of use as towns around the world develop into cities—it could help planners in such places better understand upcoming needs.

This is a weird one. But is the conclusion, that we can treat cancer, but putting Democrats in charge of it, to ruin it?

Government also grows in ways similar to metastatic cancerous tumors.

Coincidence?

When tumors get too large the core often dies and the dying cells push the outer porting of the tumor to metastasize and spread. Our urban cores have been dying for 30 years now so get ready for a wild ride.

LOL, that might work. But you know what would happen.

First they would tax it. Initially, that would help starve people with cancer reducing the number of living cancer patients.

Then they would recognize it as a tax revenue source and they would start promoting cancers. importing cancer patients, giving out free carcinogens, putting carcinogens in our water and food supply and in our vaccines and medicines.

I’m sure someone will say the growth of cities is due to white supremacy and is therefore racist.

Big cities becoming cancers on the earth?

That’s racist! (Think about it.

Good point.

Actually, there is a much better argument for that, than most the things they say are racist. Try to shove a captive voting block into a bas neighborhood, and create the conditions to make it worse. Checks out.

Probably applies to radical political groups and fringe pseudo religious groups as well.

Depending on the politics of local government, big cities tend to go bad downtown and then reach a point of demolition and new construction.

If it’s a collectivist government, downtown becomes an outdoor pharmacy.

I’m going to have to pay attention to this one. The article has David Levinson as a co-author. He is a “name” in transportation engineering circles.

Thx for posting.
