How do we know where the moon came from? In this episode, Howtown dives into the giant impact hypothesis (the least bad theory of lunar origin) and the growing evidence that the story of Theia may be more complicated than the textbook version. We explore how scientists measure the Moon’s distance, mass, and angular momentum, why Earth’s Moon is so unusually large compared with other moons in the solar system, and how Apollo moon rocks transformed the debate over the origin of the Moon. Along the way, we unpack Robin Canup’s simulations, synestia and multiple-impact, evection resonance, and the “isotope crisis”: why Moon rocks are chemically almost identical to Earth despite models suggesting the Moon should be made mostly from an impactor. From lunar eclipses and amateur astronomy to Apollo samples, South Pole missions, Theia, Artemis, Chang’e, and the search for mantle rocks, this is a deep look at moon formation, planetary science, and how scientists reconstruct what happened more than 4 billion years ago.

On January 16th of 1980, Japanese customs officials found 7.7 ounces of cannabis in Paul McCartney's luggage as he entered the country, resulting in a 10-day stay in a Tokyo prison and the cancellation of his tour of Japan with Wings.
After being released, McCartney was told never to return. Five days into his stay, reggae legend Lee "Scratch" Perry sent a letter to Tokyo's Minister of Justice in an effort lend his support.
Award-wining author Marlon James joined us to read this brilliant letter at Letters Live in New York City in June 2025.

En este capítulo, nos acompaña la activista gabonesa Honorine Mangono, otra de las grandes mujeres fuertes que visita el Tíbet con una historia difícil, pero inspiradora. Reside en España desde hace un par de décadas. Llegó buscando la asistencia médica especializada que en su país no encontró. No le quedó otra opción. Su hijo Glenn nació con una discapacidad severa provocada por una parálisis cerebral.
Honorine es una luchadora que trabaja a favor de los derechos de la infancia con discapacidad en Gabón y en otros países centroafricanos. Y lo hace a través de su oenegé "Mwana Glenn", fundada con el deseo de garantizar mejores condiciones de vida en GABÓN, y luchar contra el estigma sin alimentar estereotipos racistas.

For a while now, I've wanted to try mixing gallium and indium metal together by shoving them into each other, where something interesting should happen.
More specifically, they form an alloy that's liquid at room temperature, and when mixed with tin, they form something called Galinstan. Galinstan is a lot like mercury, and is often used as a less toxic replacement, in things like thermometers.
After building up the walls of the kiln, I have to begin a more difficult task: building a roof. Today I make a flat roof out of refractory bricks, inspired by Nils Lou's design for a Minnesota flattop kiln, for my small wood-fired pottery kiln that will hopefully reach 1300 degrees celsius, or cone 10.
I refer to Steve Harrison's "Small Portable Woodfired Kiln," Nils Lou's "The Art of Firing," and Fred Olsen's "The Kiln Book." They are all available to read for free on the Internet Archive.
I use a combination of dense firebrick and soft firebrick (IFB). There were quite a few obstacles in my attempt to build my first kiln roof, but I got through it and ended with something usable.

Tinker and Think ethos: Combining the manual and cerebral. We cannot separate the mental and the physical, nor treat any endeavor as solely mental or solely physical. But this is precisely how we have come to talk about our world—blue collar vs. white collar, intellectual vs. athlete, book worm vs. adventurer. But this is a totally false dichotomy. This channel promotes an approach that combines manual labor (pottery, carpentry, welding, bricklaying, concrete) with a smart, purposeful attitude (study, reading, science, math, poetry, and meditation). Our minds work best when they engage with our bodies. Our bodies perform best when connected to conscious mental action. Through intelligent manual work, we discover enjoyment, fulfillment, and human flourishing.
Leopoldina Fortunati, author of The Arcana of Reproduction, visited the Verso office in London to discuss the new English edition of her classic work of Feminist analysis and the truly revolutionary struggles that motivated her work.

Author Leopoldina Fortunati sat down with Sara R. Farris to discuss the new English edition of her classic The Arcana of Reproduction – now available from Verso Books.
Interview was recorded at the Verso office in London during the Historical Materialism Conference, 2025.
The Arcana of Reproduction is a foundational text and essential contribution to today’s discussions of social reproduction and the history of Italian feminism. Fortunati’s work provides some of the earliest theorizations of ‘immaterial,’ ‘affective,’ and ‘caring’ labor, and of the role of technology in reproduction, articulated decades before their popular reception in English academic literature. Reading this work some 50 years after its original publication gives us the tools to analyze the contemporary state of capitalist development and of women’s lives today. The text remains prefigurative and essential in our era of digital labor.
The Arcana of Reproduction is available now from Verso Books:

On February 28, the US and Israel launched unprovoked attacks against the Islamic Republic of Iran, unleashing a war that has rapidly escalated across the region. While Trump and Netanyahu want regime change, the Iranian regime has shown that it will not go down easily. In the face of US imperial aggression, what is the future for Iran?
Verso will be joined by Afshin Matin-Asgari, Golnar Nikpour, Eskandar Sadeghi-Boroujerdi, and Ervand Abrahamian for an urgent discussion.
The making of Makabe-ishidoro originated about 500 years ago.
Various stonework has been crafted since olden times, as good quality granite is abundant in this region.
Ishidoro is a stone lantern made of granite,
and they are placed in shrine or temple precincts prized for its exquisite carving
and solemnity, providing rustic flavor to Japanese gardens.
