How to used OpenAI's ChatGPT to creat your own custom GPT

 

By Oloruntoba David

I was never afraid to train an AI chatbot on my writing, because OpenAI had already broken the seal. CEO Sam Altman announced the “GPT” feature at OpenAI’s first developer day in November, prior to the company’s five days of leadership chaos. Before the release of custom GPTs, ChatGPT with web browsing was already able to plunder my writing for answers to questions about everything, from using better prompts to understanding niche creepypastas.

What is a "mobius tape"?

In 1858, August Ferdinand Möbius, to prove his theory about orientability, created an object that to this day still generates some discussion among specialists: this object is the Mobius tape.

 
This item was originally introduced in 1865, it highlighted the importance of geometric illusions from a topological point of view. 
The ribbon came about as a result of studies on the geometric theory of the polyhedron, carried out by Möbius while serving as a professor of astronomy and higher mechanics at the University of Leipzig, Germany. The object consists of an item with "only one side" in a loop format, where if the manipulator placed a finger on the material and followed the path without escaping the face, it would return to the starting point after two complete turns.

The invention, which is nothing more than the joining of two ends of a strip of paper after undergoing a rotation, is a unilateral product that is impossible to determine which is the top and bottom, the inside and out. According to mathematicians, these are the foundations of a "non-orientable object" that may well draw parallels with concepts of time and alternative realities.

The Möbius strip is the clearest representation of infinity, both because of the traditional format as we know it, and because of the property of not having a path with a beginning or an end, but infinite, where one has the impression of running eternally along a two-sided strip. .

Apart from its importance in the studies of orientation and geometric positioning, the Möbius

strip

also makes great contributions to topology, an extension of geometry that serves to designate a family of sets, giving the first airs to the concept of continuity. Scientists in the field study properties of objects that are preserved when moved, bent, stretched or twisted, without cutting or gluing the parts.

This proposal comes with important implications and brings new ways of studying the natural world, helping to develop number theory.

Who was the most wronged scientist in history?

The most wronged scientist in history? Oh, I have two nominations here.

At first, I was going to answer Satyandranath Bose.

The man behind the fifth state of matter, the Bose-Einstein condensate.

The man behind the Higgs-Boson particle also called “God Particle”.

The man behind Bose-Einstein statistics which laid the field for quantum statistics.

And yet the man without a much deserved Nobel Prize in Physics.


Satyendranath Bose (1 January 1894 – 4 February 1974)

The irony. Although seven Nobel Prizes were awarded for research related to S N Bose's concepts of the boson, Bose-Einstein statistics and Bose-Einstein condensate, Bose himself was not awarded a Nobel Prize.

But another Bose may just have the claim here.
A biologist. A botanist. A physicist. And one of the earliest writers of Science Fiction.

He invented the Crescograph which measured response of plants to stimuli, scientifically proving that parallelism between plant and animal tissues. In simpler language, he was the first to demonstrate that plants have life, like any other life form.

Currently, you may be reading this on your smartphone via the internet through EDGE/HSPA or WiFi. All of which uses radio waves for communication. Guess who was the first to figure out the potential for wireless communications via radio waves?

Bose was the first to use a semiconductor junction to detect radio waves, and he invented various microwave components, which are present in almost every technology that we use in our daily lives yet scarcely noticed.

5G is the talk of the town now. A critical component of which is the millimeter wave. Guess who is credited with discovering millimeter length electromagnetic waves and that too even a century ago?

A man who was reluctant to patent anything to his name. A man who valued availability of science and knowledge over monetizing it.

And the man with phenomenal contribution across multliple disciplines is none other than Acharya Jagdish Chandra Bose.


There could have not been scientists more wronged in history, so much deserving yet snubbed by the Nobel Prize.

Who is the greatest mathematician of the 21st century?

I would go for this man here

his name is Terence Tao.
Some facts about his early life and career:

He started to learn calculus when he was 7, at which age he began high school.
By 9 he was already very good at university-level calculus.
By 11, he was thriving in international mathematics competitions.
By 20 he earned his Ph.D. from Princeton University, and he joined UCLA’s faculty that year. UCLA promoted him to full professor at age 24.
His paper “The primes contain arbitrarily long arithmetic progressions” has been awarded as one of the 100 most important discoveries in all of science for 2004.
In 2006, at the ge of 31, he was awarded of the Fields Medal for “his contributions to partial differential equations, combinatorics, harmonic analysis and additive number theory”
Some thought about him from other colleagues:

“Someone like Terry comes along once every few decades”
[Tony Chan, dean of the Division of Physical Sciences and professor of mathematics at UCLA University]
“Terry wrote 56 papers in two years, and they’re all high-quality. In a good year, I write three papers.”
[John Garnett, professor and former chair of mathematics at UCLA]
Tao's mathematical knowledge has an extraordinary combination of breadth and depth: he can write confidently and authoritatively on topics as diverse as partial differential equations, analytic number theory, the geometry of 3-manifolds, nonstandard analysis, group theory, model theory, quantum mechanics, probability, ergodic theory, combinatorics, harmonic analysis, image processing, functional analysis, and many others. Some of these are areas to which he has made fundamental contributions. Others are areas that he appears to understand at the deep intuitive level of an expert despite officially not working in those areas. How he does all this, as well as writing papers and books at a prodigious rate, is a complete mystery. It has been said that Hilbert was the last person to know all of mathematics, but it is not easy to find gaps in Tao's knowledge, and if you do then you may well find that the gaps have been filled a year later.
[Timothy Gowers, mathematician at Statistical Department in Cambridge]
"If you're stuck on a problem, then one way out is to interest Terence Tao"
[Charles Fefferman professor of mathematics at Princeton University]

What is the most interesting mummy or preserved corpse you've seen and why?

The head of Diogo Alves

Diogo Alves was a 31-year-old man Spanish man who got executed in 1841. He was born in 1810 into a peasant family, he received a head injury at a young age after falling from his house. When Diogo was 19 years old he was sent off to work in Lisbon, Portugal. He frequently changed jobs and was known to enjoy drinking and gambling.

A few years later he decided to become a serial killer in Lisbon where he murdered 70 people between the span of 1836 - 1840. His modus operandi included robbing poor and less fortunate people he came across on the streets, then he would blindfold them and force them to the top of high structures (the aqueduct) where he would throw them off high falls below, making their deaths appear to be suicides. As you can tell, Diogo was not a good man and his actions were nothing short of evil.

People of Lisbon took notice of many dead bodies appearing at the bottom of the aqueduct, first, they were attributed to copycat suicides as Diogo would have liked them to believe. However quickly, when people testified and the actual evidence grew. It wasn’t long before Diogo’s murders caught up to him.

Diogo Alves was arrested, tried, and sentenced to death for murder. He was officially executed on February 19, 1841. That’s the end of Diogo Alves, right? Not exactly.

Due to some early serial killer psychology fascination, the head of Diogo Alves was severed from his deceased body in an attempt to study his brain and perhaps understand what occurred in the mind of Mr. Alves. His head was preserved in a jar, where it still resides to this very day. An entire 180 years later.

It’s fascinating to see the face of a man who lived almost 200 years ago, his facial features and youthful appearance remain. You can still clearly see his long red hair, pasty-white skin, and his icy blue eyes which now eternally stare forward
