Don’t Remove Baby’s Body Hair

A new born baby may have fine and soft hair in its body. This hair is called lanugo.

Many newborn babies have a lot of body hair. Body hair on newborns is not a cause for concern, and it usually goes away a few months after birth. Nature will take its course to let the hair shed by itself.

Lanugo is believed to help keep the baby warm. At an early gestation (The period of time that a baby develops inside its mother's body; the process of developing inside the mother's body) babies do not have a lot of fat stores and the lanugo may help maintain an appropriate body temperature.

You might hear that rubbing a ball of wheat dough (atta loi) over your baby's body will help to remove body hair and prevent it from being hairy later in life.

Rubbing atta will not permanently remove hair. They will grow again. Rashes may form on the baby’s skin.

Also, there are many home remedies to remove body hair of babies. These home remedies use milk, turmeric, flour, and other common household ingredients that have no harmful chemicals. There is no scientific evidence to suggest that they work effectively in removing body hair, but they have been used for a long time by our elders, and are a part of traditional remedies used by mothers.

These methods may not permanently remove the hair from your baby, so you may notice the hair growing back after some time.

You don't have to do anything special to treat the lanugo on your baby.

Time is the best treatment for newborn lanugo. Leave your baby’s hair alone and it will eventually disappear. In a few days or weeks, your newborn should lose lanugo. If it lasts longer, that can still be normal.

Do not wax, shave, or use a body hair remover to get rid of your baby's lanugo. These products are not safe for infants and could harm their delicate skin.

Massaging the area of skin very gently with mild baby oil might help expedite lanugo falling out, but use extreme care to prevent damaging your baby’s skin. Only use products that will not irritate your baby’s skin or eyes.

Gently massaging a baby’s skin after birth can facilitate the removal of lanugo. But this is not necessary. Massaging can be effective. But it is risky. A baby’s skin is delicate. If you inadvertently rub your baby’s skin too hard or too much, this can cause soreness, redness, or dryness. Therefore, it may be more beneficial to leave the hair alone and allow it to shed on its own.

Many full-term babies lose all their lanugo before they are born, but some do not. Whether your baby’s lanugo falls out before or after they're born, it will eventually go away. When it does, another type of hair will grow in its place. The new hair is called vellus hair.

Vellus hair is similar to lanugo but thinner and not as noticeable. This hair will cover your baby’s body throughout childhood. (Vellus hair is the light, short, fine hair that covers much of a person's body. Its length and thickness will vary from person to person. The primary role of vellus hair is to protect the skin and keep the body warm.)

What is Buoyancy?


This video explains the concept of Buoyancy.

From: https://www.youtube.com/watch?v=khc2wUBsFU4

What is Buoyancy?

Buoyancy is an upward force exerted by a fluid on an immersed object in a gravity field.

In fluids, pressure increases with depth; hence, when an object is immersed in a fluid, the pressure exerted on its bottom surface is higher than the pressure exerted on its top surface.

This difference in the pressure leads to a net upward force (buoyancy force) which opposes the gravity force and is equivalent to the weight of the fluid that would otherwise occupy the volume of the object, i.e. the displaced fluid.

Thus, if the object is less dense than the fluid, the buoyancy force will be higher than its weight and the object will float; on the contrary, if the object is denser than the fluid, it will sink.

The static balance occurs when the weight of the immersed part of the object is the same as the weight of the displaced fluid, i.e. the densities coincide.

Remark that the density of the object is meant in an averaged way, as a simple ratio between mass and volume of the immersed part.

The most common case is the immersion of a solid into a liquid (e.g. ships in the sea), but that’s not all: a rising bubble (gas in liquid), a falling droplet (liquid in gas) and aerostats (warm air into cold air) are examples of phenomena ruled by buoyancy forces as well.

Surface Tension - Why are drops spherical?


Topic: Surface Tension
Why are drops spherical?
Because personally, I am fond of spherical shapes as compared to squares.
No.
It is because of surface tension.
Surface tension is the property of liquids by which surface molecules of a liquid try to hold the liquid together by acquiring minimum surface area and acting like a stretched membrane.
You know what, everything just went over my head.
Alright. I will explain.
Inside a drop, each water molecule is pulled with a force by its neighboring molecules.
As these forces are equal and opposite, they get neutralized.
However, the molecule present at the surface is not attracted outwards.
It is attracted only inwards and sideways.
Sideways forces get neutralized.
But because of the inward force, each surface molecule contracts to form a shape that has minimum surface area which is a sphere.

Fibonacci Sequence in Nature


Fibonacci Sequence

Individuality -- the trademark of any artist, designer, or architect, each desires a uniqueness to their creation, a quality that separates it from any other.  Man naturally has this individuality.–his fingerprint. There are 6.5 billion people on the face of the earth and no two fingerprints are the same.  Everything we touch or make contact with is branded with a small expressed image revealing to all who see it - Who was there! 

Around 1200 AD  a man named Leonard Pisano, better known as Fibonacci, discovered a sequence of numbers that created a very interesting pattern.  The sequence begins with the numbers 1, 1, 2, 3, 5, 8, 13, 21, 34, and continues indefinitely.  Each number is obtained by adding the last two digits together.  A rectangle with the length and width of any two of the numbers of this sequence forms what is known as the golden rectangle, a perfect rectangle.  A golden rectangle can be broken down into squares the size of the next F numbers down and below.  If we were to take a golden or perfect rectangle, break it down into smaller squares based on Fibonacci’s sequence, and divide each with an arc, the patterns begins to take shape.   We begin to see Fibonacci’s spiral…the spiral in and of itself is insignificant; its importance is revealed in where we find it.

Take for example the sunflower the display of its florets are in perfect spirals of 55, 34 and 21 -  sequence of  Fibonacci; the fruitlets of the pineapple creates the same sequence;  the pine cone does the same.  As currents move through the ocean and the tide rolls onto the shore,   the waves that bring in the tide, curve into a spiral that can be mathematically diagrammed onto a plot:  1, 1, 2,3,5,8,13,21,34 and 55.

Buds on trees, sand dollars, starfish, petals on flowers and especially the nautilus shell are formed with this exact same blueprint.  With each segment of growth, the nautilus adds to itself one more value on Fibonacci’s scale.  This blue print can be seen around us on a small scale every day.  But the greatest example of all is directly above our heads.  At an average of 100, 000 light years across, even the spiral of the galaxies above us are formed with the exact design that the tiny shell is formed. This sequence, our blueprint, appears to be the trademark of a Designer, a proof of a Creator, something left behind Indicating the One who is there – a fingerprint.   As we span our universe from the tiny flower to the awe inspiring galaxies, we see the fingerprint of God.  And we are forced to ask:  “Who is God?”

Advanced Search Operators with Google



Andreas describes and demos some of the advanced search operators that Google uses to find exactly the data you want! (Most of these will work in any browser / search engine, by the way!)
From: https://www.youtube.com/watch?time_continue=35&v=fAQwWwZ8fs4&feature=emb_logo

A search operator or a search parameter is a character or string of characters used in a search engine query to narrow the focus of the search. ‘Search Operators’ are specific commands we can use in search engines to refine search results. Search operators are powerful and can save searchers a lot of time, especially since most operators can be used together.

Operator
Description
Example
site:
Get results from certain sites or domains.
olympics site:nbc.com and olympics site:.gov
link:
Find pages that link to a certain page.
link:youtube.com
related:
Find sites that are similar to a web address you already know.
related:time.com
-
When you use a dash before a word or site, it excludes sites with that info from your results. This is useful for words with multiple meanings, like Jaguar the car brand and jaguar the animal.
jaguar speed -car or pandas -site:wikipedia.org
"
When you put a word or phrase in quotes, the results will only include pages with the same words in the same order as the ones inside the quotes. Only use this if you’re looking for an exact word or phrase, otherwise you’ll exclude many helpful results by mistake.
"imagine all the people"
OR
Find pages that might use one of several words.
