“How can we make heaters that do not require a surrounding medium?”

 

Heating is a common need everywhere. However, sometimes our surrounding medium might not be a good heat conductor or we may not have a medium at all! So how can we make a  heater which is not affected by the surrounding environment? Well, let’s think back to basic physics. We know that infrared is a form of light, and light is able to pass through anything. So what if we were to take some metallic wires, wire them around an element, and then apply electricity to heat the element to emit infrared? Well, it turns out that this invention is a little device known as an infrared heater. Infrared heaters are classified by the wavelengths they emit (ranging from 760 nm down to a minuscule 1 nm!) and are used everywhere from cooking kebab to warming outer space missions.

“So what can walking do for you?”

 

 

  • Do you ever feel a bit gloomy or sad? Well, maybe all you need is a nice brisk walk. Studies have shown that taking time for a nice brisk walk can activate the release of chemicals which work to boost your mood and make you happier. (Rosenberg, Yael 2016)
  • Would you like to feel smarter? According to research by the Beth Israel Deaconess Medical Center, individuals that commit to a regular workout stimulate the growth of nerve development. (Goldstein, Lev 2016)
  • Want to prevent or reduce the risk of developing heart disease? Since walking is an anaerobic exercise, your heart will be strengthened by it. And with a stronger heart, you will be able to better resist the development of heart issues such as heart disease (Rosenberg, Yael 2016)
  • Want to lose weight? Nearly any type of exercise will cause you to lose weight. Through walking, you can burn off those calories that you have been holding in for a long time, allowing for a healthier weight range. (Goldstein, Lev 2016)
  • Do you ever just want to relieve yourself of some stress? Walking is cardiovascular in nature and can commence stress reducing endorphins to develop and takes your mind off the harmful things in life. (Rosenberg, Yael 2016)

Pseudoscience in health marketing

“How can we identify pseudoscience in health marketing?”

 

People become sick from time to time. And when people become sick with an unknown illness, they often become desperate for anything that sounds like a cure. And as such, malignant individuals will try to take advantage of people’s confusion and lack of knowledge. So to save your health, time, and money, here are some warning signs for pseudoscience in health marketing

 

 

  • Claims of being “natural”

 

Many pseudoscientific health products try to justify their existence with the claim of being “natural”. (Senapathy, Kavin 2017) Supposedly, being composed of natural ingredients means that this product is safe and healthy for use and works better than the “artificial” industrial alternatives. However, just because something is natural or comes from a plant does not mean that it has any useful qualities. Uranium and parasitic fungi are natural but don’t offer anything good for us

 

  1. Claims of being based on “ancient knowledge”

Since pseudoscience marketers are often unable to explain their products using modern scientific theories, they will often retort that their material is based on “ancient” or “forgotten” knowledge/wisdom (Ernst, Edzard 2013). However, previous generation’s knowledge of the natural and social world was often flawed (see geocentric universe, flat earth, and racial “science”) and are not a substitute for the fruits of current empirical endeavors.

 

  1. Claims of being “untestable”

Testability of a hypothesis is one of the most important aspects of the scientific method. (Thompson, Bruce 1997) If something can not be tested, then it can not be accepted as a scientific phenomenon and must be avoided until such procedures are possible

 

  1.   Claims of being a wide ranging cure

Since pseudoscience plays on the fears of ordinary people, vendors will often make bold claims about the healing powers of their product. However, such claims are usually unfounded, and if one logically thinks about it, if these items were so useful wouldn’t they be selling like hot cakes? For more info, look up “too good to be true” (Gauch, Hugh G. 2003)

 

  1. Claims of conspiracy

When pressed to explain their lack of widespread success, alternative health marketers will often retort that there is a “conspiracy” to keep them down. These are usually a desperate attempt to rationalize their product’s niche nature, and never based on reality. (Gauch, Hugh G. 2003)

“What organisms carry diseases to others?”
Diseases are everywhere, whether it be in plants, animals, or fungi. However, what is the term for organisms that transmit diseases? Well, after many years of study, Epidemiologists have termed organisms that transmit diseases vectors (Kind of like the mathematical construction found in physical and engineering sciences). Any organisms can be a vector, including humans!

“Is it possible for a town to save money by installing a microgrid?”
One of the biggest criticisms of microgrids is that they are too expensive to implement. However, the town of Sterling, Massachusetts proves that wrong. Sterling Massachusetts has recently installed a 2-megawatt battery attached to a microgrid with a 3-megawatt solar panel that can support the town’s police station and emergency dispatch center for at least two weeks in case of an emergency situation. During peak use, the batteries can discharge and power homes, eliminating the need for external energy transmission. This technology saves the town up to $400K per year and is attracting visitors from Japan to Germany. Read more Sterling here.

“What is Malaria?”

 

Mosquitos spread all sorts of diseases. However, one of their more infamous ones is known as Malaria. Malaria is characterized by high fevers, chills, and muscle pain. Malaria can be treated with medicines, but are not always effective due to possible bio-resistance by certain strands of the Malaria parasite. Malaria is commonly found in Asia, Latin America, and Africa

“How can we heat spaces using gas?”
With space heating, we can keep our buildings at a warm temperature no matter the weather outside. However, what is one way that we can implement this? Well, let’s use our engineering mindset to find out. We know that processes in nature can raise their temperature using convection. So why don’t we just imitate this and use convection heating? To do this, let’s take some air, and channel it across a heating element to warm it up, and then mix it into a local space. This method is widely used across buildings worldwide.

“How can we keep spaces in buildings warm?”

 

Buildings are the most common form of shelter for humans. They can provide simple comfort, warmth, and protection from the exterior world. However, they are subject to variations which make them less habitable, such as unwanted changes in temperature. So how could we use our engineering mindset to solve this problem? Well, we know that most of the heat in buildings is caused by the gaseous atmosphere inside it. So what if we were to pump a gas with a higher temperature into the living space? Well, this is the fundamental idea behind space he ing, and is used everyday by people all over the world

“What is the modern method for surveying?”

 

Surveying through triangulation can be a painful and arduous task whose accuracy is limited by larger distances. So how can we make a rethink of surveying methods to take into account modern technology? Well, let’s use our engineering mindsets to think about it. We know that we can control the emission of light and microwaves and that these can reflect off surfaces all while moving at the speed of light. So what if we were to use this timed response to infer the distance traveled between two points? Well, this method for surveying is known as trilateration and has become widely used in civil engineering
