WHO GOT THE FOCUS ON?
The light bulb is one of the inventions that revolutionized history, but the authorship of its invention is still a matter of debate
On October 21, 1879, in the United States, Thomas Alva Edison first demonstrated the electric lamp with a bulb that was on for 48 hours.
On December 24 of that same year, Edison presented a circuit made up of 40 incandescent light bulbs in his laboratory in New Jersey, which he himself turned on and off to the astonishment of the more than 3,000 people who gathered.
And barely a month and days later, on January 27, 1880, Edison obtained the patent for the light bulb. The office that was in charge of registering the inventions gave him the number 223 thousand 898.
The controversy came when other inventors such as Joseph Swan, Humphry Davy or Henry Woodward showed that they had also invented the bulb before Edison.
Humprhy Davy in 1809 connected a carbon filament to the two poles of a battery, producing light. Years later, in 1820, the British chemist and astronomer, Warren de la Rue, changed the carbon filament to platinum, connected to two electric poles inside a glass body. Despite working better than Davy’s, the high cost of that material prevented its success.
The race to invent the light bulb continued and in 1835 James Bowman Lindsay built a lamp that allowed him to read a book in the dark.
Following these advances came Joseph Wilson Swan, a British physicist and chemist, who already in 1850 worked with filaments of a chemical element called tungsten and carbonized paper inside a glass bulb. This work made him obtain the patent for Great Britain for the light bulb in 1860.
After seeing how his invention was not recognized by almost anyone in the world, he joined forces with Edison in 1881 and founded the Edison & Swan United Electric Light Company Limited. This company is credited with improving the focus, providing it with new elements that allowed its durability over time and the beginning of mass manufacturing.
The great forgotten of all this history is Nikola Tesla. The Serbian engineer is for many people the true inventor of the light bulb, since thanks to him alternating current was discovered, which made light bulbs more durable. In 1884 he began working with Edison, with whom he clashed from the start. For this reason he was always in the shadow of the American inventor.
FACT
223 thousand 898, is the number that Thomas Alva Edison obtained for the patent of his light bulb, in January 1880
WHILE YOU SLEEP, YOUR BODY DOES NOT REST
Some strange things that happen to us without realizing it because we are asleep: movements that we did not know and even walking while asleep
When we go to sleep our mind deals with dreams, but the body continues to function. During the night, the brain receives a great energy boost and activates, our blood pressure drops, breathing slows, we grow… and many other processes.
Hence the importance of sleeping well. Although, with today’s increasingly busy pace of life (so many things to do!: study, answer the phone, play on the console), sleep may seem unnecessary, but just because you are not awake, does not mean that you are not awake. things are happening in your body.
During those 8 hours of sleep, we go through different stages in which the muscles relax and slow eye movement begins.
Second, brain waves are slow—with some rapid variations—and both our heart rate and blood pressure become irregular.
The third stage is when the brain waves transform into slow, high-amplitude restorative waves. During this time the bodies begin to repair themselves. Power is restored.
Finally, at this stage our brain also blocks memories and archives the information it absorbed the day before.
whet your appetite
As we fall asleep, the digestive system causes hormones called leptin and ghrelin to balance. The first removes hunger and the other provokes it. If we don’t get enough sleep, that balance could be upset. That is why those who suffer from insomnia see their appetite affected.
restless eyes
Eye movements are one of the best known things related to bedtime. It is when the eyelids take care of cleaning: the rheum that accumulates in the corners of the eyes are waste cells and residues, such as bacteria or dust that we catch when we blink.
A “stretchy”
When sleeping, the body releases the hormone somatotropin, which is responsible for the growth and repair of muscles and bones, taking advantage of the fact that our muscles are more relaxed.
On the defensive
The immune system builds up defenses while we sleep, fights infections, and even produces a protein that could kill cancer cells.
Zero stress
The pleasant relaxation that we feel when sleeping is due to the fact that cortisol levels (a stress-related hormone) decrease.
FACT
reveal?
Full sleep and a good rest make us have many benefits. Now you will think twice about staying up late watching the episodes of “Merlina” that you have pending.
LIGHTS THAT POLLUTE
Find out who it hurts and what you can do about this problem that, despite its exaggerated way of attracting attention, “happens overnight”.
Light pollution is an ecological problem that, unlike plastic pollution or the effects of climate-altering gases, is almost never discussed in public. It is that permanent lighting at night by artificial light sources and the associated effects on us and the environment.
Light poles, advertising signs and night lighting in public and private buildings also contribute to the phenomenon, as well as lighting in private homes, stadiums, gardens and balconies.
In cities, the clearest “symptom” of light pollution is that you cannot see the stars in the sky. But he is not the only one: turning night into day has very serious repercussions.
How did we get there?
For millions of years, life on earth was determined by the rhythm of day and night. Consequently, the life of the animal and vegetable worlds, and obviously, that of Humanity, adapted to the natural phases of light and darkness that change throughout the year.
However, for a relatively short period of time, we (Humanity itself) have broken the cycle with artificial light sources, with consequences that are hardly noticeable at first glance, but can sometimes be serious.
How affects?
Humans belong to the creatures that live by day and, in a “normal” state of affairs, we need the night to rest. Constant lighting alters the natural rhythm of day and night and causes, among other things, disturbances in the production of sleep-related hormones and numerous physiological processes that occur during the night.
In turn, all of the above increases the risk of obesity, metabolic disorders and cancer, among other diseases. Similar effects can be observed in many animals and plants.
Also, if we stop seeing the stars in the sky, our relationship with the environment changes. Blindness to planets, shooting stars, and the Milky Way makes us more lonely and isolated from our natural environment.
On the other hand, lighting at night is a waste of energy and money, and reveals our low environmental awareness.
harmed animals
Migratory birds that follow the stars on their way to their winter roosts are distracted by night light sources and can lose their bearings. In addition, artificial light also has a negative effect on the rhythm of life of birds in general.
Songbirds begin to sing earlier in the day. Breeding and mating behavior changes, and their sleep is affected.
Also, about half of the insects are nocturnal. To perform their important ecological task as pollinators and to feed and reproduce, they depend on natural darkness.
Instead of being protected by starlight, they are drawn to lamps and other sources of night light and either die of exhaustion or are easy prey for predators. Light pollution is one of several factors contributing to increased insect mortality and the general decline in biodiversity.
plants too
Even plants react to artificial light with changes in their life cycle and, for example, start to form leaves and flower earlier under artificial light.
City trees illuminated by streetlights have been shown to delay leaf fall in autumn, a natural response to lower temperatures that protects them from frost damage.
On the other hand, in gardens illuminated at night, the plants produce fewer flowers and, consequently, fewer seeds. A circumstance that in turn can affect their reproduction and pollinating insects.
These are just a few examples that show how massive and diverse the effects of artificial lighting are across the ecosystem. Many consequences of light pollution have not yet been adequately investigated and the interactions, for example, between animal and plant life are so complex that the effects can hardly be assessed.
Put your grain of sand
Choose lighting with a switch, motion detector or timer and only activate it when you really need light.
Install outdoor lighting as low as possible to attract fewer insects and birds.
Bet on a soft and warm light. In any case, it is better to use several weak lamps than one bright one.
Avoid artificial lighting as much as possible on the outskirts of towns and in nature reserves.
FACT
Attentive!
In cities, the clearest “symptom” of light pollution is that you cannot see the stars in the sky. But he is not the only one: turning night into day has very serious repercussions.
