Blood falls

In 1911 year one Australian scientist Griffith Taylor discovered vivid red falls in a glacier named after him. This Taylor Glacier is 1.5 million years old and 54 kilometres wide. From this glacier red coloured water’s flowing onto the Lake Bonney.

It looks scary, like blood coming out from under the huge glacier. For first scientists thought it to be due to brine flowing through the glacier or it was thought to be cause of red algae. However, after 2003 it is said red colour came from oxidized iron most likely draining from a 5 million year old lake underneath the glacier. So iron oxide in reaction with salt water and air gives us the red colour. But how salty, blood-red water can flow from  dry old glacier to the waterfall in the region well known for its sub-zero temperatures? Well, the scientists from University of Alaska Fairbanks and Colorado College claim the get an answer. They say that it happens because water gives off heat when it undergoes the phase change from liquid to frozen. So under that glacier is an ancient lake with iron rich water. When the water flow out due to heat it undergoes it comes into contact with air and turns into a reddish brown shade or oxidizes (rusting) .

Do not worry, just remember that your happiness is the state of your mind. What you think about situation and how you react is what makes your mood. Just think positive and believe in good. “Good” is everywhere. One day you unhappy, another day you are happiest person in the world. Just do not worry and Be YoRsELf.

Tips for travelling

Okay, so right now I am a traveller and I have some advices for you. I have had a long long days on the road and certainly will be ready fully for the next trip. So if you are going somewhere and got your luggage full check on your “to do” list. Do not forget to include there:

  1. Take a lot of food and beverages. You will certainly get hungry!
  2. It is better to have some extra clothes like socks or t-shirt so you are ready to change if you spill something, get dirty or just simply if you sweat.
  3. Do not forget to take antiperspirant because you won’t smell like a bunch of just collected roses. That’s for sure.
  4. Check the weather of the place where you are heading. You can put warm clothes on the top of your luggage if it is going to be cold there or vice versa.
  5. Napkins! Wet, dry, natural, not natural, just take napkins!

6.Take a travel pillow if you have one, it will make sleeping more comfortable.

If you are going to have a really long trip check my “yoga for travellers” post where you will find few easy poses while sitting and standing that will make you feel better and fresher like a cucumber.

peace ✌️

Aloha!! I haven’t been making any posts for few days. Sorry! Right now I am pretty busy and have no idea when I’ll be able to post anything. Do not forget to visit my blog and wait for amazing news :3

Peace

 

Aloha! Yesterday was my day off ahaha so I didn’t post anything. Today you can expect few freshly new posts about science and something else. As you can remember I am reading the book “blogging” and there is a lot of really useful tips and advises. I recommend it if you want to start blogging. But from reading about all this I understood that blogging not that easy and it takes a lot of hard work, patience and of course knowledge. So as I am just a beginner I want to start very very slowly, start with small steps. So do not abandon my blog because it is slow or not developing. I am sure I will turn out some cool cucumber blogger in no time at all! Hahaha

I love you my cucumbers! (If anyone reads at all) ahahahaha

and just for showing off look at this huge lovely pile of books I am reading all at the same time! I just love it 😍  IMG_0250

And today we are making “sloppy joe”, check “food and recipes” tonight :))

Peace ✌️

Medical Robots

Our world is rapidly developing around us and it is not a big surprise to see a surgical robot…well, actually for me it is a surprise. My sister sent me an article about a robot that makes stitches better than professional human surgeon. One of those robot experiments took place in Children’s National Medical Center in USA, they made a robot STAR. It can make stitches by itself with no human help. Robot uses computer sight, fluorescent markers and 3D cameras. According to images it gets it chooses the right technical program of stitching and gets it done with machine accuracy.

I think it is very good for people, because they will be more convinced on the operation’s quality since robots are gonna be more accurate. But on the other hand what will happen to human surgeons themselves? If imagine a world where human surgeons are old-style and robots make most of the surgical operations…well, for first it is kind of creepy to me because I think that there is a possibility that artificial intelligence can some day dominate over humanity. HA-HA. But everything can happen. I wouldn’t want to make even a step into the “humanless” hospital.

However, with people observing all this it seems pretty cool to be operated by a robot. It is easier, because neatly done surgical operation is achieved with big patience and a lot of practice for a human, plus huge amount of time since a human should study the theory to get to practice…when it takes only some time to calculate and make a surgical robot.

Black holes

We imagine black holes as the huge monsters devouring everything on their way. “Big cosmic vacuum cleaners”. Actually they hide a lot. What is inside a black hole? Are the wormholes- time and space travel shortcuts real?

Let’s begin with the last stages of a dying star. A massive star begins to die when it runs out of its internal thermonuclear fuels in its core. After that it starts to shrink inward upon itself  under the force of gravity. The outer layers of the star are blown away and the core turns into a point of zero volume and infinite density called the singularity. The border of this singularity called event horizon. Nothing, not even light can escape this singularity which means go through the event horizon. Escape velocity is the speed of light. However, a black hole won’t “suck” you into itself, at least not until you come too close to its gravitational field, event horizon. So if you appear to be floating near such a giant, make sure you are not close enough to the event horizon to be sucked in.

We got all details of the structure of the black holes by calculating the theory of relativity. According to Einstein’s theory of relativity the space-time looks like grid. And objects that have mass make a curvature in it as shown on the image.

Actually not every star after dying turns into a black hole. It depends on the mass of the star. There was one scientists who predicted the existence of stellar bodies that emit no radiation. He predicted it in 1916 and his name was Schwarzchild. Also he predicted a radius of event horizon. Schwarzchild radius is that , foe instance, a star with a mass of 10 our suns will collapse and become a black hole, event horizon of which would be only 30 kilometres. Can you believe it? So the stars no less than 3 masses of our Sun will turn into a black hole after collapsing under its gravity. But if the mass is less, it means the star will become either a white dwarf or a neutron star. Our star- sun, will become a white dwarf according to theories.

” Black hole are black! How can you proof that they even exist?”- you might ask. Well, the answer is pretty easy. Also the black holes are invisible themselves, the effect of their enermous gravitational field on nearby matter is pretty obvious. We can see the envelopes of gas swirling around the black holes at it extremely high velocities.

But there are black hole that are made not after the death of star. There exist black holes that were made in the beginning of the universe and they are small (Hawking). Maybe even died by now.Some of them are made after the collapse of large volumes of interstellar gas. Gas collapses at the centres of quasars or galaxies. One such black hole is Sagittarius A*. This black hole was made of a star with mass of about 4310000 masses of our sun. And this black hole is the centre of our Milky Way galaxy. In 1994 Hubble Space Telescope found a black hole that was a star with more than 6 billion masses of our sun.

Watch this video to get more sense how big black holes can be..

 

I just came from the library with two new books on spectrums and evolution of our universe. I am working on the post about black hole, kind of my favourite topic 😻 so wait for the great posts explosion, ha-ha

Yesterday I had a brain jump and have got an idea. I am making a group of volunteers to clean our streets. For now it is just an idea, hopefully few weeks later my plan will come true. I will post about it later saying what and where it will take place.

Peace ✌️
