The Fallacy of Airplane Mode Disabling the Global Positioning System Tracking of Smartphones

Leave a comment

Even when Airplane Mode is activated, the Apple iPhone still receives signals from the global positioning system because this apparatus is a passive, receive only system which does not rely upon a cellular connection, WiFi connection, and/or Bluetooth connection to function. The iPhone scans and listens for satellites orbiting the Earth and calculates its relative position based upon this timing data, which means the iPhone can still determine a users location even without an internet connection, however if this is not desirable by the end user, Location Services can be disabled which theoretically turns this function off. This information is true for most modern smartphones including Android, however not all (e.g. smartphones manufactured prior to 2010, minimalistic/budget conscious smartphone designs, smartphones with custom firmware and/or enterprise restrictions like those managed by corporate information technology teams or running custom read only memory etc.)

The Reason WD-40 Was Developed

8 Comments

The WD-40 formula was developed by 3 scientists who succeeded in their goal upon the 40th design attempt, with the name WD-40 being an acronym meaning “Water Displacement: 40th Formula”. WD-40 was created in 1953 by the Rocket Chemical Company located in San Diego, United States of America. The formula was originally researched and developed as a means to protect the outer skin and thin tanks (e.g. lightweight pressurized tanks which provide structural support when filled saving weight overall) of SM-65 Atlas intercontinental ballistic missiles from rust and corrosion during the manufacturing, handling, and storage process(es) of missile silos. This proprietary mixture resolved for the aerospace industry the need for a dependable water displacing solvent which prevented moisture and other related damage. Early use of WD-40 upon Atlas SM-65 missiles demonstrated the solutions superior effectiveness in comparison to analogs. This prompted a handful of employees to take canisters of WD-40 home which inadvertently inspired the projects founder, Norm Larsen, to package WD-40 in an aerosol form designed specifically for consumer use. WD-40 first appeared on store shelves in 1958 and developed applications in spacecraft maintenance, disaster recovery, and countless home and industrial tasks (eg. lubricating stuck hinges of seized doors, displacing moisture upon electrical contacts, loosening rusted and/or seized bolts etc.)

The Mathematical Probability of Miracles

Leave a comment


Many would argue that miracles have a 1:1,000,000 (1 to 1 million) ratio, and others whom are more conservative would argue that miracles have a 1:1,000,000,000 (1 to 1 billion) ratio, meaning for every 1 miracle, 1,000,000,000 (1 billion) events occur without a miracle. 1 in 1,000,000,000 (1 billion) sounds astronomically high, as on the entire planet there are only 8,100,000,000 (8.1 billion) human beings, but if a person draws 6 cards from a standard deck of cards, whatever sequence they draw has a 1:14,000,000,000 (1 in 14 billion) chance of occurring. Because of this, one could argue that every hand of cards drawn is a miracle and not a random act of chance. This logic applies to all randomized items or numerical values (e.g. first 6 digits of a Social Insurance Number or last 6 digits of a phone number etc.). What humans refer to as a “miracle” is often merely a statistical anomaly, an event with low probability, but not impossibility, something which is guaranteed to occur given enough repetitions are made. The sheer volume of possible outcomes virtually guarantees that rare patterns will emerge eventually, not because they are miraculous, but because the mathematics demand it be so

The Origin of Google’s Name

Leave a comment

Google’s original name was “BackRub”, a reference to its early algorithm which analyzed backlinks to assess their importance. Backlinks are the hyperlinks pointing to webpages on the internet (e.g. navigation from one website to another etc.). Developed at Stanford University in 1996 by Larry Page and Sergey Brin, BackRub laid the foundation for PageRank, the ranking system which would later power the Google search engine. As the project matured, Page and Brin began to recognize and understand that the name BackRub did not reflect the vast scope of their ambitions for the company as the duo wanted a name that could capture the enormity of the data their engine could and eventually would process. This is why the name “Google” was chosen in 1997. Interestingly, during a domain search for “googol.com”, a mathematical term which represents 10¹⁰⁰ (10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 or 1 with 100 0’s after it) the friend who registered the domain name for Page and Brin accidentally typed “google.com” instead of “googol.com”. Originally this was an error but Page and Brin believed the misspelling to be simpler, more memorable, and visually cleaner therefore deciding to keep the name as it was

How Credit Scores Work Within North America

Leave a comment

Credit is a complex issue, influenced not only by individual financial behavior but also by institutional frameworks, socioeconomic conditions, and evolving market dynamics that shape how credit is accessed, evaluated, and/or sustained. 35% of ones credit score is due to payment history; paying on time is crucial to having and maintaining a healthy credit score. 30% of ones credit score is due to what they owe, primarily in relation to how much credit they have and how much credit they owe (eg. allotted $25,000 and used $20,000). Going over 30% of ones allotted credit is a red flag for creditors and lowers ones score. 15% of ones credit score is due to the length of time in which the person has had some form of credit which is why it’s important to start and build up credit early in adult life. 10% of ones credit score is due to how many times credit was opened; multiple openings or inquiries in a short period may signal risk but repeated openings of new credit or repeated attempted openings of new credit shows that the person in question constantly requires more and more credit and is at a higher risk to not be able to pay back a loan. Finally, 10% of one’s credit score is due to what kind of credit they have. Having a balanced credit history of vehicle loans, student loans, mortgage loans, and credit card loans is more favorable than having only a single credit card loan all by itself as it shows the ability to manage diverse credit types

The Argument Against Private Corporation Umbilical Cord Blood Storage

Leave a comment

Canadian Blood and Tissue Bank Insception Life Blood claims that 80 life threatening diseases (e.g. various cancers, metabolic diseases, immune diseases etc.) can be treated with umbilical cord blood, and that these diseases have been treated with success for over 2 decades, with over 45,000 pediatric transfusions worldwide. The majority of these transfusions however were accomplished due to public cord blood banks. Physicians can tap into worldwide public registries with nearly 1,000,000 (1 million) donors to find a match for a patient and this service is free. In the setting of leukemia or a genetic defect, physicians would want to use cord blood which is not biologically related to the patient to avoid having the problem continue. The American Academy of Pediatrics states, “private storage of cord blood as biological insurance should be discouraged”. There is a caveat to this however, in the case of a child having a genetic defect, it is recommended that the family save the cord blood of the next child, if another child is born. It is believed that private cord blood corporations leverage fear, uncertainty, and timed pressure to cajole families into deciding to privately store cord blood. Insception Life Blood has stored cord blood from 70,000 infants yet only 14 were released for transplant, a value of 1 in 5000

The Industries Disrupted by U.S. Entrepreneur Steve Jobs and U.S. Inventor Thomas Edison

Leave a comment

Steve Jobs affected and subsequently disrupted the computer industry, the motion picture industry, the music industry, and the telecommunucations industry, all within a single lifespan. This achievement places Jobs at the status of a world renowned icon, a person like Thomas Edison who affected all of the same industries as well, swapping only the computer industry for the electric industry. Edison invented the incandescent light bulb for the electric industry, the phonograph for the music industry, and the motion picture camera for the film industry, and improved the telegraph and telephone for the telecommunications industry. Jobs developed the Macintosh computer for the computer industry, the animation studio Pixar for the film industry, the iPod and iTunes for the music industry, and the iPhone for the telecommunications industry

How Antique Books are Forged and How to Detect Replica Antique Book Forgeries

Leave a comment

Modern day forgers are able to replicate rare books printed using a mechanical printing press by using photopolymer plates, a process which involves taking a high resolution photograph of a page which was printed using a printing press and allowing computer software to create a three dimensional printed image of that photograph with depth for each letter present. This method produces pages which have an imprint mark as if pressed by a printing press but its fatal flaw is that it also provides depth to small lines around the margin of text which are picked up during the printing process. These lines should have no depth as they are merely extra ink which has been caught during the printing process but with photopolymer replicas, because the software used to extract three dimensional characters reads every single bit of ink as a marker to place depth, these lines appear to have depth within forgeries which is an immediate red flag in terms of authenticity as originals have no reason to possess depth. These incidental inking lines around the margin of the page are referred to as “shoulder inking”, and if they possess depth of any degree, it is a strong indication that the piece is a modern day forgery

The Etymology of “ChatGPT” and How Artificial Intelligence Models are Developed

Leave a comment

OpenAI’s artificial intelligence “ChatGPT” is named as such because of the acronym “GPT” which stands for “generative pre-trained transformer”. The generative pre-trained transformer provides the characteristics of any large language model like ChatGPT. The term “generative” refers to an artificial intelligences “ability to generate new content which is similar to the data sets it was trained upon”. The term “pre-trained” refers to the “practice of artificial intelligence models being fine tuned for specific tasks, a pre-training phase in which the large language model learns from a vast amount of text data which helps the model understand language patterns and contexts”. The term “transformer” refers to the transformer architecture which is a “neural network design that relies upon a mechanism referred to as “attention” to weigh the influence of different parts of the input data”. This transformer architecture is particularly effective for tasks which involve understanding the context of language (e.g. language translation or answering questions etc.) which is why artificial intelligence models are able to understand human language in a deep and complex way
