Right now, 820 million people aren’t getting enough calories on a daily basis to lead a healthy lifestyle. As a global issue, several countries worldwide are still facing stagnation today with their levels of hunger.
Unfortunately, some countries have even been getting worse.
In Canada, when a teenager needs to get an immunization or a bandaid we usually just go to a school nurse or a family clinic. They’re very easy to reach and use, especially if you live in an urban area. You can almost always trust your doctor or nurse to give you the appropriate treatment you need and give qualified health advice.
Unfortunately, this is rarely the case for developing countries. In developing countries, the budget, prioritization, and social support around a highly functional healthcare system is often very low.
A solution that many developing nations are exploring is a…
Before last Monday, I’d always thought of philosophers as wise scholars packed with knowledge. Reading into some of the teachings of Socrates, Plato and Nietzsche was enough evidence for this conclusion.
However, ever since looking into Rene Descartes my perspective has changed. In case you don’t know, he was also a philosopher — as well as a mathematician and an interesting guy. Unlike other philosophers I’ve researched, he wasn’t super knowledgeable about much. My idea of a philosopher has been challenged.
Don’t get me wrong, he’s still super smart. Despite not knowing a ton, he was an extraordinary thinker —…
I’m a total newbie to philosophy. Friedrich Nietzsche is the first philosopher I’ve deeply researched.
One word: wise.
Two words: super wise.
Three words: really super wise.
I’m still so impressed by how smart people like him are. I found a lot of Nietzsche’s philosophies groundbreaking and fascinating.
Here are some key ones that I strongly agree with and disagree with.
Nietzsche sometimes talked about people who had dedicated their lives to avoiding pain. These people were sages → someone who’s attained the wisdom a philosopher seeks. They thought pain is certain, but suffering is optional. Sages trained their minds…
Rainforests are some of the most interesting landscapes on the planet. They’re our oldest living ecosystems, with some having survived in their present form for over 70 million years. Interestingly, while they only take up 6% of Earth’s landmass, rainforests are home to half of the world’s flora and fauna species.
“A rainforest is simply an area of tall, mostly evergreen trees and a high amount of rainfall.”
These collections of ecosystems have even more interesting qualities. Rainforests help both humanity and the environment; through climate regulation, providing resources, and more.
However, these invaluable but fragile areas are under attack…
If you’re anybody anywhere right now, you know about the coronavirus. Because of fear-mongering and culture-shocking-cuisine, the social panic has been around for a while — but after being labeled a pandemic, tensions have shot through the roof. With governments advocating for isolation and social distancing, almost (but hopefully) everyone is locked inside their homes.
We know first-hand that the virus has significantly impacted our day-to-day lives, but what’s less discussed is COVID’s impact on industries. Current and future implications are both interesting and scary. While countries worry…
You read the title correctly. We’ve heard of classical and quantum computing, but promising research and work suggest that future supercomputers will consist of biological components.
Biocomputing, or organic computing, is an emerging field of computation that’s completely different from anything we’ve seen before the 21st century — and the area is still rapidly emerging.
So what specifically is biocomputing, and how does it work?
The word biocomputing is pretty self-explanatory — computing systems that use biological materials. While computational biology means modeling biology on computers, with biocomputing, biology becomes building blocks for computers. …
In 1928, the first-ever true antibiotic was discovered by Alexander Fleming. Returning from a vacation, he’d accidentally discovered that his petri dishes had been contaminated by green mold. Now referred to as penicillin notatum, the substance had been killing growing bacteria — and, after further testing, it was found capable of destroying other kinds of bacteria. By preventing bacteria from forming cell walls, they were unable to grow.
Since then, we’ve come a long way. Antibiotics are now routinely used by people across the planet, with its anti-bacterial benefits helping to keep society healthy. …

Using this dataset, I created a neural network capable of classifying breast tumors. The features are measured characteristics of cell nuclei within the tumor, including perimeter, concavity, and smoothness. The labels are 0 or 1, representing benign and malignant diagnoses respectively. With my network, I mapped the relationship between these two variables.
We’ll first import the following libraries.

In all neural networks, the core architecture consists of neurons within several layers; input, hidden, and output. As data is propagated throughout the network, weights adjust their values and help the net make a final prediction of some kind.
Weights and biases are commonly known for nets, but less popular is the concept of activation functions.
In this article, I’ll discuss what these functions do, different types of them, and their use cases. Let’s go!
Activation functions are functions we apply to the input…
