Science & Technology🌱People are trying to find out plenty of solutions how to help our enviroment ... Today I saw this interesting idea, but I'm really curious about your opinion.. Do you think it is better to invest in something like this or better to find a place for plant a tree?
Also tree has few more advantages.. Shadow and biodiversity... But still my opinion is that every drop into the sea will help a little.. So, let me know.. 🌱😉
The solution
Dr. Ivan Spasojevic, Ph.D. in Biophysical sciences, and one of the authors on the project from the Institute for Multidisciplinary Research at the University of Belgrade, developed an innovative tool for reducing greenhouse gas emissions and improving air quality: the liquid tree. Also dubbed LIQUID 3, the novel creation is Serbia’s first urban photo-bioreactor, a solution in the fight for clean air. It contains six hundred litres of water and works by using microalgae to bind carbon dioxide and produce pure oxygen through photosynthesis.
The microalgae replace two 10-year-old trees or 200 square meters of lawn. The function of the LIQUID 3 is practically an imitation of it. Both trees and grass perform photosynthesis and bind carbon dioxide. However, the advantage of microalgae is that it is 10 to 50 times more efficient than trees. The team behind LIQUID 3 has stated that their goal is not to replace forests or tree planting plans but to use this system to fill those urban pockets where there is no space for planting trees. In conditions of intense pollution, such as Belgrade, many trees cannot survive, while algae do not have a problem with the great levels of pollution.

Every year before Easter, we have a habit of cutting a few birch twigs.. We put them in water and in two weeks it looks like this..
In a few days, the children will hang Easter eggs on them (they gradually make them at home.. Nice, what do you think?😊)
And now that I've already boasted about how clever my children are 😁🤭, I'll get to the point...
Have you knew about great health benefits of birch leaves??🍃
They contain vitamins, minerals, tannins, essential oils and substances with an antibiotic effect..
🍃A decoction of these leaves has significant diuretic effects - it promotes urination, but does not burden or irritate the kidneys. Therefore, the decoction is useful for those who suffer from kidney and urinary stones. Among diuretics, birch is recommended for cleansing and treating the urinary system..
🍃It can also help in the fight against rheumatism, as the decoction promotes salt excretion. The healing power can also be demonstrated for joint or muscle pain. In addition to the decoction, you can also use birch oil to rub painful joints, skin or muscles..
🍃It also supports hair growth..
🍃So you can prepare tea, hair wrap or oil and use it almost for free for few health benefits..
💡Science is constantly bringing new knowledge, but I think that people in the past had tremendous knowledge and many of them can be considered scientists with the ability to use the power of nature.. What do you think??
All photos are mine but I used some help about informations from this source..
@mmk3y Science & Technology Science & Technology Science & Technology Science & Technology Science & Technology Science & Technology Science & Technology 🌳We already know that nature is just full of plastic trash.. It is almost everywhere..and I'm not saying about that big one, visible, which we can at least pick up.. But about microplastics.. In water worldwide, into the soil, and unfortunately also into almost all living creatures..
Bigger parts is easy to pick up and take it to the landfill.. But you can hardly see those little and micro parts.. It is there until now..
🤷🏼♂️So for the beggining I only wanted to show you some of my own photos..
But now try to imagine that plastic, in some mysterious way, also get into the geology of our Earth.. Actually, you don't even have to imagine it.. 😂 Here is an example..
The geology of Brazil’s volcanic Trindade Island has fascinated scientists for years, but the discovery of rocks made from plastic debris in this remote turtle refuge is sparking alarm.
Melted plastic has become intertwined with rocks on the island, located 1,140 km (708 miles) from the southeastern state of Espirito Santo, which researchers say is evidence of humans’ growing influence over the earth’s geological cycles.
“This is new and terrifying at the same time, because pollution has reached geology,”
- Fernanda Avelar Santos, a geologist at the Federal University of Parana.
Santos and her team ran chemical tests to find out what kind of plastics are in the rocks called “plastiglomerates” because they are made of a mixture of sedimentary granules and other debris held together by plastic.
“We identified the pollution mainly comes from fishing nets, which is very common debris on Trinidade Island’s beaches. The nets are dragged by the marine currents and accumulate on the beach. When the temperature rises, this plastic melts and becomes embedded with the beach’s natural material.” - Santos said
Trindade Island is one of the world’s most important conservation spots for green turtles, or Chelonia mydas, with thousands arriving each year to lay their eggs. The only human inhabitants on Trindade are members of the Brazilian navy, which maintains a base on the island and protects the nesting turtles.

Amazing isn't it?? 🤓🧴🌳 Or sad??
Tell me your opinion..

Intro to the enviromental (clickable link) 3y Science & Technology "In times of yore, a couple of lovers who loved each other deeply despite the rivalry of their families, decided to get married, but on the big day so special for both, the father of the bride took a rifle and shoots the groom propitiating him the death instantaneously, this act caused the bride wrapped in tears and with a huge grief to run out with her beautiful dress towards the mountains, and being there when she could not bear the sadness of losing her beloved, she made a pact with the Apu and the Pachamama, which turned it into a beautiful waterfall, so that everyone could appreciate its beauty for all eternity “
- Peruvian legend
La Cascada de la Novia
This beautiful waterfall you will love for sure, the waterfall “Cascada La Novia“, is located in the city of Cajamarca, Peru, in the town of Namora.

And in what do we believe?
💧Is it necessary to back everything up with scientific data, such as here that water flows in a given formation because of the shapes of the bedrock? Or is it sometimes appropriate to believe the local people who have inhabited the area for centuries?🤷🏼♂️
💧Children are those beings who usually don't overcomplicate things. When I read this rumor to them, and showed them also this post about existence similarities, the younger one said:
"I thought that the waterfall was created by chance, but now I know that nothing in nature and in the universe is accidental..."
If you will find some time, try to read this to your kids, I'm very curious what they think about it.. And if you don’t have kids, I'm also curious about your opinion.. 😉💧
@mmk3y Science & Technology Science & Technology Maybe you don’t know about me that I'm paraglider.. At least I was, becouse I was not flying for few years.. I know I know.. Dangerous and crazy.. 😁 But also fun and you need great knowledge about meteorology and Principles and technique of flying.. You have to learn how to find rising thermal currents if you want to fly for a longer distance..
🤷♂️And who are the masters of thermals?? Birds of pray!! Many paragliders are observe them during their fly and copy their flying ways.. Without flapping their wings, they can fly long distances and raise heights of many meters..
And then Scott Mason in 2001 came with an idea:
Parahawking was developed by British falconer Scott Mason in 2001, with the expert advice of Stephen Hawking, whose name was an inspiration for the activity. Mason began a round-the-world trip in Pokhara, Nepal, where many birds of prey – such as the griffon vulture, steppe eagle and black kite – can be found. While taking a tandem paragliding flight with British paraglider Adam Hill, he had the opportunity to see raptors in flight, and realised that he could combine the sports of paragliding and falconry.
The team started by training two black kites, but have since added two Egyptian vultures, Kevin and Bob, to the team. Only rescued birds are used – none of the birds have been taken from the wild.

Amazing what do you think? Now I have to return to this beautiful sport again and maybe when I will meet some eagle, I will train it.. 🦅🤪
@mmk3y Science & Technology I'm making this post for @InnaT, but I'll be happy if you all join the discussion.. Many times you've seen a bunch of rocks stacked just like that, but sometimes into shapes or chimneys, that your mind stops, how is this possible?
🤷♂️If you want to start with this, you will have to use basic physical principles: center of gravity and counterweight.
🎯The center of gravity is basically the place or point where there is an equal amount of weight on all sides. So any time you want to balance something, you're actually going to have to find its center of gravity. To balance a rock, the Center of Gravity must be directly above where it touches the underlying rock.
If your rock tower has one small rock at the bottom and you're trying to balance the bigger rock on top to hold the bigger rock, just place it so that its center of gravity is over the smaller rock, the area of contact. This is easier said than done. This is where balance comes into play.
Source of picture above
🤭If you want one stone to stick out at an odd angle, the center of gravity of that stone does not have to be above the contact area, but you can place the second stone on the other side so that the center of gravity of both rocks combined is above the contact area. This is how they will balance each other.
And of course, you can try to balance almost everything.. Good example is this guy:😂🤭
🤪So I'm waiting for your photos and videos from balancing something ..

What is the most mysterious objects we know? 🤷♂️For me and for many scientists it is a Black hole... Supermasive objects with so huge gravity, that even light can't escape..
I believe there will be few more posts about black holes, it is so interesting with their singularities etc.
But today I want to show you what will happen in the near future..😊
Source of image
In three years, 2 giant black holes will collide and we will witness it from Earth.. The merger of black holes is a very rare astronomical phenomenon, and the fact that we will be able to observe it from the ground with telescopes is very exSCITEing..💡
The weird behavior of a galaxy around a billion light-years away suggests that it might contain one of the most highly anticipated events in modern astronomy.Fluctuations in light from the center of the galaxy SDSS J1430+2303 look suspiciously like a pair of supermassive black holes with a combined mass of around 200 million Suns destined for an imminent collision with each other.
Imminent" in cosmic terms can often stretch on for whole lifetimes. Fortunately in this case, astronomers predict that if the signal is indeed the result of colossal black holes they will merge within the next three years.It may be our best shot yet to see two supermassive black holes collide… but we still don't know for sure if that's what is going on at the heart of J1429+2303. Scientists advise that we continue watching the strange galaxy to see if it can be conclusively identified.

@mmk3y Science & Technology Science & Technology 🚘When we see the sign Rolls-Royce, we first imagine a luxury car... but did you know that this company also deals in aviation technology and turbine engines on a large scale?
🔹The company announced the development of a small nuclear reactor to help with space travel and building bases on the surface of the moon..
🔸The special reactor, which the company called the Micro-Reactor, will be designed to survive the harsh conditions of space travel. Uranium is supposed to be under several layers of protective packaging, and it is supposed to be the most important product of Rolls-Royce's space division. However, it should not only be used for travel, but also for living on other space bodies.
🔹The Rolls-Royce reactors are supposed to function, for example, as power plants for future bases or colonies on the surface of the moon or even Mars. The company has also released an image that shows the potential appearance of such a fission reactor, but for now it is only a preliminary design and it is working with the UK Space Agency on the study. We will wait for the final version.
🔸Such reactors can help space transport, especially in connection with ion propulsion. The latter is mainly used by satellites, or China's new space station or the upcoming Gateway station, which the US wants to place in an orbit around the moon in cooperation with other countries. But the ion drive uses electricity and needs a lot of it to unlock its true potential.
🔹Carrying large solar panels with you is impractical for such drives, as they are dynamically stressed during acceleration, when the electrical energy is consumed the most. This can be solved by fission reactors, which, although heavy, can, after sufficient miniaturization, drive powerful ion drives that are capable of shortening the journey to Mars to just a few tens of days.

Not just for space🔸Rolls-Royce develops reactors not only for space use, but even for use on Earth. Small reactors working on nuclear fusion - tokamaks - are still the music of the distant future, so I think, this is great alternative.. Specifically, it deals with smaller modular reactors that are supposed to help with the climate crisis by making clean energy available at a much lower cost and with much greater construction flexibility.
🤷♂️But would we believe such a technologies? Nuclear fission has a huge number of opponents, even though it is only one of the most cleanest energies.. After all, there are certain risks..
I am curious about your opinion..😉💡

Nuclear energy - intro post3y Science & Technology Hi there.. ☺️🙋♂️
🤖AI causes us a great deal of enthusiasm, admiration, but also worries about the future... We can already watch intelligent robots, intelligent chatbots, deepfake technology etc... But look at what a young engineering student Priyanjali Gupta came up with... I think it's also amazing when it's definitely just the beginning..
The driving factor was her mum, who asked her "to do something now that she's studying engineering", a statement echoed by most Indian mums..
"She taunted me. But it made me contemplate what I could do with my knowledge and skillset. One fine day, amid conversations with Alexa, the idea of inclusive technology struck me. That triggered a set of plans,"
"The dataset is made manually by running the Image Collection Python file that collects images from your webcam for or all the mentioned below signs in the American Sign Language: Hello, I Love You, Thank you, Please, Yes and No,"
"The dataset is manually made with a computer webcam and given annotations. The model, for now, is trained on single frames. To detect videos, the model has to be trained on multiple frames for which I'm likely to use LSTM. I'm currently researching on it,"
- Gupta
Gupta credits her model inspiration to data scientist Nicholas Renotte's video on Real-Time Sign language Detection.
