Nature is filled with threes. Land, sea, and air. People propagate many plants by three chief methods. These methods are: (1) cuttage, (2) grafting, and (3) layering. Forests a catagirized into three major groups: (1) coniferous forests, (2) temperate deciduous forests, and (3) tropical rain forests.

What’s happening at the center of the Trifid Nebula? Three prominent dust lanes that give the Trifid its name all come together. Mountains of opaque dust appear near the bottom, while other dark filaments of dust are visible threaded throughout the nebula. A single massive star visible near the center causes much of the Trifid’s glow. The Trifid, cataloged as M20, is only about 300,000 years old, making it among the youngest emission nebulas known. The star forming nebula lies about 9,000 light years away toward the constellation of the Archer (Sagittarius). The region pictured here spans about 10 light years.

Closest to the Sun on March 1, and closest to planet Earth on April 23, this Comet ATLAS (C/2020 R4) shows a faint greenish coma and short tail in this pretty, telescopic field of view. Captured at its position on May 5, the comet was within the boundaries of northern constellation Canes Venatici (the Hunting Dogs), and near the line-of-sight to intriguing background galaxies popularly known as the Whale and the Hockey Stick. Cetacean in appearance but Milky Way sized, NGC 4631 is a spiral galaxy seen edge-on at the top right, some 25 million light-years away. NGC 4656/7 sports the bent-stick shape of interacting galaxies below and left of NGC 4631.
The rule of three has become something akin to a social law of gravity — as if the number is behind everything.
Three groups of experimentalists have independently observed a strange state of matter that forms from three particles of any type and at any scale, from practically infinitesimal to infinite.
Forget pairs. They’re old pat. And 42? We still don’t know the question.
Comedians insist three is the best pattern to exploit perceptions and deliver punchlines; three features prominently in titles, such as The Three Little Pigs, Three Musketeers, Goldilocks and the Three Bears; even the Romans believed three was the ultimate number: “Omne trium perfectum” was their mantra — everything that comes in threes is perfect.
Now, it seems Mother Nature may also think in threes. Especially at the very edge of physics — quantum mechanics.
A Soviet nuclear physicist first proposed the idea back in the 1970s — and was met with derision.
For 45 years number-crunchers around the world have been attempting to topple Vitaly Efimov’s idea and prove his equations wrong.
They’ve failed; and his “outlandish” theory is now on the point of being proven.
Most importantly, Efimov felt that sets of three particles could arrange themselves in an infinite, layered pattern. What form these layers take helps determine the makeup of matter itself.
Jump forward four decades, and technological advances now allow his groups of three quantum particles to be studied and manipulated.
The quantum condition — now known as Efimov’s state — is visible only under supremely cold conditions. Matter, when chilled to a few billionths of a degree above Absolute Zero, does strange things …
The World Health Organisation (WHO) has published an updated guidance on the use of face masks for control of COVID-19.
In his opening remarks at a media briefing on Covid- 19 last Friday, WHO Director-General Dr Tedros Adhanom Ghebreyesus said the guidance is based on evolving evidence, and provides updated advice on who should wear a mask, when it should be worn and what it should be made of.
He said WHO has developed this guidance through a careful review of all available evidence, and extensive consultation with international experts and civil society groups.
“I wish to be very clear that the guidance we are publishing today is an update of what we have been saying for months: that masks should only ever be used as part of a comprehensive strategy in the fight against COVID.
“Masks on their own will not protect you from COVID-19,” he emphasised.
He said the updated guidance contains new information on the composition of fabric masks, based on academic research requested by WHO.
“Based on this new research, WHO advises that fabric masks should consist of at least three layers of different material. Details of which materials we recommend for each layer are in the guidelines.”
According to the latest guidelines, cloth masks should consist of at least three layers of different materials: an inner layer being an absorbent material like cotton, a middle layer of non-woven materials such as polypropylene (for the filter) and an outer layer, which is a non- absorbent material such as a polyester or a polyester blend.
“Fabric cloths (e.g., nylon blends and 100 percent polyester) when folded into two layers, provides 2-5 times increased filtration efficiency compared to a single layer of the same cloth, and filtration efficiency increases 2-7 times if it is folded into 4 layers. Masks made of cotton handkerchiefs alone should consist of at least 4 layers, but have achieved only 13 percent filtration efficiency. Very porous materials, such as gauze, even with multiple layers will not provide sufficient

When will stocks reach the low and what will the recovery look like?
Credit Suisse said it needed to see three conditions required for a trough in global stocks:
1. Clear-cut fiscal easing in the U.S. — which happened late on Sunday;
2. A peak in daily infection rates
3. A trough in global purchasing managers indexes, which it said could happen in May.
In the severe acute respiratory syndrome crisis, markets bottomed out a week daily new infections hit a peak, the bank’s research analysts said.
“We expect a V-shaped recovery ultimately and would be buyers of equities on a one-year view; we believe markets will rise 15-20% over the next 12 months.
“Historically when we look at exogenous supply-side shocks, markets tend to rise very rapidly from the trough (SARS, Kobe earthquake, Suez, 1987),” they said.
The analysts, led by Andrew Garthwaite, favored stocks in Asia (a commodity-importing region on top of the virus) relative to Europe. In a new realistic worst-case scenario, U.S. earnings would drop 20% and the S&P 500 would fall to 2,200 points, they added.
They also expected “massive” monetary and fiscal stimulus. “This should enable a V-shaped recovery that by the end of 2021 could make up for much of 2020’s lost growth,” they said.
Excerpt: Scientists studying the novel coronavirus are quickly uncovering features that allow it to infect and sicken human beings. Every virus has a signature way of interacting with the world, and this one — SARS-CoV-2, which causes the disease covid-19 — is well-equipped to create a historic pandemic.
The coronavirus may take many days — up to 14 — before an infection flares into symptoms, and although most people recover without a serious illness, this is not a bug that comes and goes quickly. A serious case of covid-19 can last for weeks.
This coronavirus can establish itself in the upper respiratory tract, said Vincent Munster, chief of the Virus Ecology Section of Rocky Mountain Laboratories, a facility in Hamilton, Mont., that is part of the National Institute of Allergy and Infectious Diseases. That enables the virus to spread more easily through coughing and sneezing. Munster and his colleagues have been studying the novel coronavirus under laboratory conditions to better understand its viability outside a host organism — in the air and on surfaces.
Those experiments found that at least some coronavirus can potentially remain viable — capable of infecting a person — for up to 24 hours on cardboard and up to three days on plastic and stainless steel.

up the duff. (Britain, Australia, New Zealand, Newfoundland, colloquial, slang) Pregnant. The expression UP THE DUFF originated in Australia in the 1940s.
Duff. If you describe something as duff, you mean it is useless, broken, or of poor quality. “Sometimes you have to take a duff job when you need the money.” [British, informal, disapproval]

The N-P-K ratio is the percentage by volume of nitrogen (chemical symbol N), phosphorus (P), and potassium (K) in fertilizer. A 16-16-16 fertilizer, for example, contains 16% nitrogen, 16% phosphorus, and 16% potassium.
How is NPK Calculated?
To calculate the pounds of nitrogen in a bag of fertilizer, multiply the weight of the bag by the percent nitrogen (this is the first number in the N-P-K designation on the front of the bag). Then divide the pounds of nitrogen by the area the bag states it will cover to get the pounds of nitrogen per 1,000 sq. ft.
Roles of NPK
The first number of the ratio indicates the amount of nitrogen in the fertilizer. Nitrogen serves a few different roles but its primary benefit to grass is to help produce lush, green leaves. The second element is phosphorus, which is focused on more of the downward growth and fuels important developments such as root growth. The final nutrient represented in the ratio is potassium. This particular nutrient focuses more on resistance. If you already have an established lawn that’s starting to suffer from stress or diseases then the application of potassium is crucial to the health of the grass.
What’s the Best Ratio?
The NPK ratio represents is the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. So how do you what’s best for what ratio? Here are some basic rules to follow. If you are starting a new lawn then get lawn fertilizer that has a higher percentage of phosphorus and potassium. At this stage, it’s important to focus on root development and disease resistance.
If you are installing a new layer of sod then apply a similar ratio to what you would use for new lawns. Although new sod does have established grass, the roots themselves have been shaved off so it is vital to up the amount of phosphorus in the soil for root development purposes.
Finally, if you are well into the gardening season and have an established lawn then focus on using a fertilizer that has a higher composition of nitrogen. Before Using Lawn Fertilizer perform a test to determine the amount of nutrients that already exist in the soil. This can be done on your own through the use of NPK soil test kit.
It’s been said that we really only fall in love with three people in our lifetime. Yet, it’s also believed that we need each of these loves for a different reason.
Often our first is when we are young, in high school even. It’s the idealistic love—the one that seems like the fairy tales we read as children.
This is the love that appeals to what we should be doing for society’s sake—and probably our families. We enter into it with the belief that this will be our only love and it doesn’t matter if it doesn’t feel quite right, or if we find ourselves having to swallow down our personal truths to make it work because deep down we believe that this is what love is supposed to be.
Falling In Love the 2nd Time: The Hard Love
The second is supposed to be our hard love—the one that teaches us lessons about who we are and how we often want or need to be loved. This is the kind of love that hurts, whether through lies, pain or manipulation.
We think we are making different choices than our first, but in reality we are still making choices out of the need to learn lessons—but we hang on. Our second love can become a cycle, oftentimes one we keep repeating because we think that somehow the ending will be different than before. Yet, each time we try, it somehow ends worse than before.
Sometimes it’s unhealthy, unbalanced or narcissistic even. There may be emotional, mental or even physical abuse or manipulation—most likely there will be high levels of drama. This is exactly what keeps us addicted to this story line, because it’s the emotional roller coaster of extreme highs and lows and like a junkie trying to get a fix, we stick through the lows with the expectation of the high.
With this kind of love, trying to make it work becomes more important than whether it actually should.
It’s the love that we wished was right.
Falling In Love the 3rd Time: The Love that Lasts
And the third is the love we never see coming. The one that usually looks all wrong for us and that destroys any lingering ideals we clung to about what love is supposed to be. This is the love that comes so easy it doesn’t seem possible. It’s the kind where the connection can’t be explained and knocks us off our feet because we never planned for it.
This is the love where we come together with someone and it just fits—there aren’t any ideal expectations about how each person should be acting, nor is there pressure to become someone other than we are.
We are just simply accepted for who we are already—and it shakes to our core.
It isn’t what we envisioned our love would look like, nor does it abide by the rules that we had hoped to play it safe by. But still it shatters our preconceived notions and shows us that love doesn’t have to be how we thought in order to be true.
This is the love that keeps knocking on our door regardless of how long it takes us to answer.
It’s the love that just feels right.
Maybe we don’t all experience these loves in this lifetime, but perhaps that’s just because we aren’t ready to. Maybe the reality is we need to truly learn what love isn’t before we can grasp what it is.
Possibly we need a whole lifetime to learn each lesson, or maybe, if we’re lucky, it only takes a few years.
Perhaps it’s not about if we are ever ready for love, but if love is ready for us.
And then there may be those people who fall in love once and find it passionately lasts until their last breath. Those faded and worn pictures of our grandparents who seemed just as in love as they walked hand-in-hand at age 80 as they did in their wedding picture—the kind that leaves us wondering if we really know how to love at all.
Someone once told me they are the lucky ones, and perhaps they are.
But I kinda think that those who make it to their third love are really the lucky ones.
They are the ones who are tired of having to try and whose broken hearts lay beating in front of them wondering if there is just something inherently wrong with how they love.
But there’s not; it’s just a matter of if their partner loves in the same way they do or not.
Just because it has never worked out before doesn’t mean that it won’t work out now.
What it really comes down to is if we are limited by how we love, or instead love without limits. We can all choose to stay with our first love, the one that looks good and will make everyone else happy. We can choose to stay with our second under the belief that if we don’t have to fight for it, then it’s not worth having—or we can make the choice to believe in the third love.
The one that feels like home without any rationale; the love that isn’t like a storm—but rather the quiet peace of the night after.
And maybe there’s something special about our first love, and something heartbreakingly unique about our second…but there’s also just something pretty amazing about our third.
The one we never see coming.
The one that actually lasts.
The one that shows us why it never worked out before.
And it’s that possibility that makes trying again always worthwhile, because the truth is you never know when you’ll stumble into love.
