  The Story of Astrophysics in...

  When Neil Armstrong first set foot in the lunar dust, the Earth held its breath. That one small step forever changed our view of what was possible, sparking a dramatic expansion of humankind's cosmic awareness. When we gain a new perspective, a transformation begins, profoundly altering the understanding of the world our human experience had previously granted us. 
   
   
   
  In The Story of Astrophysics in Five Revolutions, astrophysicist Ersilia Vaudo explores five such turning points in the history of cosmology: Newton's realization that gravity governs the celestial world; Einstein's dual theories of relativity, linking space with time and gravity with acceleration; Hubble's revelation of an expanding, rather than static, universe; and the emergence of antiparticles from a mathematical equation and their implications for our cosmic evolution. 
   
   
   
  In poetic prose, Vaudo illuminates the key insights that have led us to where we stand now. At the same time, she urges us to look beyond—to be open to the transformative realizations yet to come in our ongoing quest to understand the extraordinary, and still largely mysterious, universe to which we belong.

  My First Cannabis Crop -...

  The use of cannabis is a practice that every day becomes more frequent around the world, mainly due to the multiple properties that the derivatives of this plant have, both in therapeutic and recreational terms. The depenalization of cannabis in more and more countries around the world has been a strong promoter of its proper use, as well as a booster for scientific research that has led to the description of the benefits it has for the control of various medical conditions such as glaucoma, anxiety, epilepsy, Alzheimer's disease, PTSD, among others. However, many legal statutes considerably limit or regulate the cultivation of cannabis, being this practice still not allowed in many countries, while in others the number of plants that can be grown at a time is considerably limited. 
  Being a plant that is usually used looking for a specific effect, generated by the set of its molecules or some of its components found in the flowers or buds, the efficient cultivation of cannabis is usually a slightly more complex task compared to other plants, as it is based on a series of procedures, which methodically hope to control all the elements involved in some way, in the growth and flowering of the same to obtain the best quality of the products derived from such crops. An example of this is the possible substitution of the time of exposure to sunlight by ultraviolet light lamps, regulated manually or through timers. Something similar happens with other factors, such as temperature, humidity, the amount of water and the richness of the soil. The modern cannabis grower must take into account all these guidelines if he expects to harvest good quality flowers, rich in cannabinoids and terpenes, balancing these substances according to therapeutic needs or tastes associated with recreational use. 
  Today, many cannabis markets offer for sale various strains of this plant, all with different properties: some rich in THC, others in CBD, some with fruity flavors and others rather earthy. The variety is immense, so another fundamental aspect is to know which strains suit the expectations, desires and possibilities of each grower. 
  And if it is a question of obtaining what is expected, determining the precise moment for harvesting is a fundamental step, since the good grower must know how to recognize the signs that the plant shows when it is in the optimal period in terms of concentration of cannabinoids and other coveted substances. 
  In this text, Pharmacology University explores the most elementary points among the details surrounding the cultivation of cannabis, from the germination of the seeds to the curing of its dried flowers to obtain a final product of the highest possible quality. This knowledge is highly valuable in the context of the growing and increasingly lucrative medical cannabis market, which is valued at nearly twenty billion dollars worldwide.

  Meteorite Hits and Near Misses

  What is a meteor or meteorite? A meteor is a small body of matter apparently from outer space that upon entering the Earth’s atmosphere resembles a streak of light, what we normally call falling stars. A meteorite is one of these that successfully hits the ground and sometimes other things, including people, buildings and animals! 
  Until 1803 most scientists regarded falls of meteorites as absurd and fantastical. As well as impossible. This was until the massive fall onto L’Aigle in France of thousands of meteorites on April 23rd 1803. Previously on November 11th 1799 there had also been a massive meteor shower comprising thousands of meteors that was seen all over the Earth. This is now known to be the Leonid meteors whose falls have diminished since. The Leonids come around every November, usually near the beginning of the month. Funny how this is a peak period for UFO sightings! That was accepted meteorites. Then you have such things as Black Comets. Black comets are extinct cometary nuclei which no longer create outgassing. No tail is visible. They are black and difficult to see in space unless they are passing celestial bodies. Even these seem apparently normal when you look at everything that has come crashing down, sometimes heavily and sometimes lightly, from the skies. Amongst the true meteorites and possible fragment of black comets, and possibly even antimatter, and even large blocks of ice, what then are the rest of these? That the majority of UFO sightings might actually be misidentified meteoric or cometary bodies. The list of incidents from the sky including numerous near misses. Are they meteors, comets or UFOs or a combination or misinterpretation of all of the above?

  Egg - A Dozen Ovatures

  An unconventional history of the world’s largest cellular workhorse, from chickens to penguins, from art to crime, and more. 
  The egg is a paradox―both alive and not alive―and a symbol as old as culture itself. In this wide-ranging and delightful journey through its natural and cultural history, Lizzie Stark explores the egg’s deep meanings, innumerable uses, and metabolic importance through a dozen dazzling specimens. 
  From Mali to Finland, mythologies around the globe have invested the egg with powers of regeneration and fecundity, often ascribing the origin of the world to a cosmic egg. An oracle to Romans, fought over by Gold Rush gangs, used as the foundation of the Clown Egg Registry, and blasted into space, the egg has taken on larger proportions than, say, the ovum of an ostrich. 
  It has starred in global dishes from the Korean comfort food ttukbaegi gyeranjjim to the less regaled yet iconic soft-boiled egg. Stark writes a biography of French-born chef Jacques Pépin through his egg creations, and weaves in her personal experiences, like attempting to make the perfect omelet or trying her hand at pysanky―the Ukrainian art of egg decoration. She also explores her fraught relationship to the eggs in her body due to a familial link to cancer, and shares her delight in becoming a mother. 
  Filled with colorful characters and fascinating morsels, Egg is playful, informative, and guarantees that you’ll never take this delicate ovoid for granted again.

  Trees have much to offer as soul friends, and their millennia of growth and loss provide deep wisdom, if we know how to pay attention. The Spiritual Wisdom of Trees encourages us to revel in the beauty and wonder of trees as they increase our capacity to bear witness to loss and grief. Integrating science and spirituality, coauthors Beth Norcross and Leah Rampy explore the knowledge held within the living world of trees and planted within each of us. 
   
   
   
  Drawing on extensive experience in both forest ecology and spirituality, Norcross and Rampy invite us into a deep mutual relationship with trees, whose wisdom provides comfort, resilience, guidance, and hope. Living amid the uncertainty of climate chaos and biodiversity loss, we experience loneliness, anxiety, grief, and fear. Such times call us to a fuller spiritual presence, richer connections to the world around us, and a deeper knowing that all are held within a sacred web of life. 
   
   
   
  Pulling from the Center for Spirituality in Nature organization's coursework, Norcross and Rampy offer us guidance and practices based on their experiences leading walks, retreats, and pilgrimages for over two decades. When we learn the ecology of the forest and how to be present in nature, our eyes are opened to the awe and wonder of our world, deepening our sense of sacred oneness.
