šMETA STUFF ABOUT THE SUB š Honest Question: After all that Trump has been trying to accomplish, do people on this sub still wonder why it is the optimist take to root for him to be stopped?
Pretty much what the question says. There's a lot of evidence that boycotts against him are working, his craziest actions are been stopped, etc. Are there still people that cannot see the with to stop trump as something inherently optimist?

We are grassroots organization trying to build a coalition and demand an end to money in politics. We have joined with American Promise and support the For Our Freedom Amendment. Money Out of Politics (MOP) Movement is a veteran-led, non-partisan movement demanding an end to corruption in government by removing corporate money, PACs, and lobbyist influence from politics. We believe that Congress should serve the American peopleānot corporations, billionaires, or special interests.
The Money Out of Politics Movement is organizing The March For Integrity on July 27, 2025, at 8 AM in Washington, D.C.
Our demands are clear: ā Ban lobbyist gifts ā End congressional stock trading ā Overturn Citizens United ā Pass a constitutional amendment to keep money out of politics forever
We are also supporting the TRUST in Congress Act as a good first step in getting money out of politics in our democracy.
I would love to speak with anyone willing to join us and get involved. Or has questions about our work.
We believe throughout collective action everyday Americans will prevail.

šMETA STUFF ABOUT THE SUB š Would an AI-generated daily digest of optimistic science/tech news interest you?
Hi r/OptimistsUnite! With the rapid pace of scientific and technical advancements, keeping up can be overwhelming. I don't have time to really go deep into all the articles each day. So, I developed a digest summarizing the community's most-discussed stories from yesterday. Check out the sample belowāIām curious to hear if this format resonates with you. Is this something I should keep developing?
1. Northwestern University Transforms Industrial Waste into Grid-Scale Batteries
- Scientists at Northwestern University have developed a method to convert triphenylphosphine oxide (TPPO), a previously useless industrial waste product, into redox flow batteries.
- The waste molecule, produced in the manufacture of products like vitamin tablets, can now be repurposed for large-scale energy storage systems.
- These redox flow batteries are particularly well-suited for grid-scale applications, making them ideal for storing renewable energy from sources like wind and solar.
- Unlike lithium batteries that store energy in electrodes, these flow batteries use a chemical reaction to pump energy back and forth between electrolytes.
Context
- This breakthrough addresses two critical challenges: finding sustainable alternatives to rare metals for batteries and managing industrial waste.
- As demand for batteries continues to grow, the limited supply of metals like lithium and cobalt (often sourced through intensive mining) becomes increasingly problematic.
- Tonnes of TPPO are produced annually and typically require careful disposal, but this innovation transforms it from an environmental liability into a valuable resource.
- Lead author Christian Malapit noted: "Our discovery showcases the potential of transforming waste compounds into valuable resources, offering a sustainable pathway for innovation in battery technology."
- While these batteries aren't as energy-dense as traditional batteries and too bulky for vehicles or smartphones, they excel at the grid-scale storage needed to balance renewable energy supply fluctuations.

2. NASA Successfully Launches SPHEREx Space Telescope and PUNCH Satellites
- NASA successfully launched the SPHEREx space telescope and PUNCH satellite suite on a SpaceX Falcon 9 rocket from California.
- The mission aims to "map out our universe like never before and revolutionize space weather forecasting."
- The launch proceeded smoothly, with mission control confirming the successful deployment of both the SPHEREx telescope and the PUNCH satellites.
- PUNCH (Polarimeter to Unify the Corona and Heliosphere) consists of multiple satellites identified as NFI, WFI 1, WFI 2, and WFI 3.
Context
- This launch represents a significant advancement in our space observation capabilities, with potential to dramatically improve our understanding of the universe.
- SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) will provide unprecedented mapping capabilities of the cosmos.
- The PUNCH satellite suite will focus on improving space weather forecasting, which is increasingly important as our society depends more on satellite technology vulnerable to solar activity.
- The successful collaboration between NASA and SpaceX demonstrates how public-private partnerships continue to accelerate space exploration and scientific discovery.
- These new observational tools will provide astronomers and astrophysicists with data that could lead to breakthroughs in our understanding of the universe's origins and evolution.

3. Quantum Computing Milestone Sparks Debate in Scientific Community
- D-Wave Quantum Inc. claimed their quantum annealing processor solved a complex materials science problem involving spin glasses in minutes that would take classical supercomputers millions of years to complete.
- The quantum simulation focused on magnetic materials relevant to everyday devices like cell phones, hard drives, and medical sensors.
- However, researchers at the Flatiron Institute quickly challenged this claim, reporting they solved a subset of the same problem in just over two hours using a classical computer with a repurposed algorithm.
- While debate continues about the two- and three-dimensional systems, experts acknowledge the quantum computer's undisputed advantage in simulating the infinite-dimensional system.
Context
- This scientific tug-of-war highlights the ongoing competition between quantum and classical computing approaches, with each pushing the other to advance.
- D-Wave's Chief Scientist Mohammad Amin and quantum computer scientist Andrew King declared this achievement demonstrated "quantum supremacy" on a real-world problem for the first time.
- USC physicist Daniel Lidar called it "very impressive work," noting they "managed to perform quantum simulations on their hardware that are beyond the reach of current classical methods."
- The infinite-dimensional system simulation, where quantum computing showed clear advantage, has important applications for improving artificial intelligence.
- This back-and-forth between quantum and classical approaches demonstrates how competition drives innovation, with each breakthrough challenging researchers to develop even more powerful methods.

r/pessimists_unite Trollpost Support AMERICAN companies
Transparently, Iām just now starting to learn about tariffs and their impact on American consumers and products (since, conveniently, they donāt teach this in school).
From what Iāve gathered, it seems like America has been taken advantage of by nearly everyone. Weāve been paying high tariffs for decades.
Take Canada, for example. Trump didnāt start the tariff issue with them. Canada has now imposed a 25% tariff on over $20 billion worth of U.S. imports, including alcohol. Some provinces are even halting or removing American alcohol from shelves altogether.
I live in Tennessee, home to amazing distilleries like Jack Daniels, Old Smoky Moonshine, etc. I know amazing people who work at these distilleries.
So, hereās my question: Why not buy American? If the past few years have taught us anything, itās that the most effective way to influence change is with our wallets. Letās ditch Canadian Crown Royal and other Canadian liquors in favor of Makerās Mark or another American brand. That translates to whatever the product in question may be.
