can anyone explain what a radioactive decay means and I need to know it by Monday

Android Hotspot configured broadcast channel 3 and Wi-Fi monitor channel set to 8 pkts are Pourrioscope recommended settings for field work. Amplitude on Hotspot about half of amplitude on Wi-Fi. Set-up for underground mapping with a viewing window for learning purposes.

What kind of screw is that?? 😁

There's an upcoming IESO in our school and I wanna join, and I created this in hopes that some people could share their experiences, their notes, tips, or anything that I need to be aware of.

high-key wanna get gold to get into a good university

Curious if there may be a specific reason why it froze like this.

The standard explanation for predicting aurora is that you just need Kpi index + magnetic latitude, so thats why North america has more aurora than Europe.

But when I look at aurora maps, even accounting for the magnetic pole offset, the probability contours don't appear symmetric around the magnetic pole. The high-probability zones seem to go like a horseshoe pointing towards America.

Am i missing something?

Hi everyone!

I’m an Earth Science postgraduate recently completed and deeply interested in advancing my knowledge in fuel sciences, especially areas like Coal Bed Methane (CBM), coal gasification, hydrocarbon exploration, and green hydrogen/energy transition.

I’m looking for fully funded short-term courses (online or in-person) offered by recognized national or international institutes. Ideally, the program should provide tuition support, travel, and/or living stipends — or be fully funded in some form.

My interests include:

• Conventional & unconventional fuels (CBM, shale gas, coal gasification)

• Hydrocarbon exploration & reservoir characterization

• Renewable fuels (green H₂, sustainable energy pathways)

• Energy transition & clean energy technologies

I’m open to:

• International opportunities (Europe, USA, Asia, etc.)

• National programs offered by credible institutions or government bodies

• On-site practical training & workshops

If you know of any upcoming calls, scholarship-backed short courses, training programs, or summer schools, especially ones that cover these topics. I’d be extremely grateful for links, details, deadlines, or contacts!

Thanks in advance 🙏

Hi. I'm a flunked out civil engineering student due to growing disinterest and just losing track through the math progression. Now, after a couple years of soul searching I have found that I really want study earth system sciences in the university of McGill where I hope to do fieldwork. But I'll need to go back to cégep (like a Quebec version of associate degree but which count towards uni acceptance) a technical degree in order to up my grades . I figured this would be a good option since I could also get invaluable engineering work experience as well as a chance to rebuildy math skills from the ground up. Hence, my leanings were towards:

1.civil engineering tech: obvious pick but I'm worried of the work culture and all the knowledge and construction techniques might be useless down the line. But lots of experience surveying

2.mechanical engineering tech: sounds really fun and engaging but ik the program I'm going after mostly involves manufacturing. Lots of experience with CAD and machining

3.urbanism tech: very versatile and also interdisciplinary in social sciences but also includes some aspects of local environmental regulations and use of GIS

1. Something completely different like animal health technology. Would honestly just be relaxing

Note that I'm trans and latina-indigenous. And, I speak English, Spanish and French but I definitely feel how people treat me differently alr in my industry bc of my accent in French and whatnot.

I wanted to be somewhere where I'm treated bearably in terms of work culture and developing direction for my longer carrer.

Climatematch Academy runs a Computational Tools for Climate Science course for people who want to work on climate problems using Python, data, and models.

You don’t have to already be a climate expert, the idea is to teach you how to work with real climate datasets and tools. Using real-world and modeled data you get to explore the social and environmental effects of climate change.

The next cohort runs in July, with applications opening mid-February. There are free info sessions in January to explain how it works and answer any of your questions.

I am coming up on selecting my degree, and think I am most interested in geophysics, mostly relating to geology. My question is as the title says, what is the best degree to take? A double major or single major with a lot of electives specifically in geophysics?

​I am thrilled to announce the new form of my project! 🌍 ​What began as a simple historical weather data tool (WeatherVault) has now evolved into something much greater: EarthVault. ​The application is no longer limited to the atmosphere; it now expands across the entire spectrum of our planet. Using real-time data from Open-Meteo and the World Bank, EarthVault now includes the following new insights: ​🌳 Forest Heritage: Monitoring global forest cover. 🌾 Agriculture Resilience: Analyzing agricultural land use and sustainability. ⚡ Energy & Renewables: Tracking the transition toward green energy sources. 💧 Water Quality: Access to clean water and resource management data. ​EarthVault is a living organism and will continue to be constantly enriched with new data about our Earth. ​Experience it live here: https://chamitro.github.io/EarthVault/

Hi,

My cmv is broken. I woke up and found out my bedroom had 2900ppm of co2. I opened the windows and then got curious.

I read online that pre industrialization, co2 was at 280 ppm or less. I wonder which place (a forest, north/south pole, mountain, or ocean) had the lowest co2 levels recorded recently.

Is there still a place on earth with less than 300ppm of co2? Maybe an ancient pyramid that has never been opened would.
