I’m a ceramicist and I’m making a calculator for glaze analysis. I want my calculator to output the co-efficient of thermal expansion of the fired glaze as calculated by the expansion of the various oxides that make up the glaze, but I don’t know (and haven’t been able to find out) if I should be calculating from the mass or molar mass percentage of the oxides. Let me know if I didn’t explain anything well enough!
Not too sure on this, could somebody help? Cheers.
Do you think that it would be a classic "illegal to get without a prescription, But no one would ever know the real reason why as there is no actual evidence and research from the government to why it's illegal" type of thing like when some life changing technology gets close to people's grasp then slowly drifts away as there always seems to be a catch to everything that's falls under groundbreaking technology vs average citizen.
I'm making a periodic table specimen collection. For carbon I could go with graphite, but I'm wondering if there is a carbon compound (a plastic, maybe) with a very high percentage of carbon (by weight or volume) that I might consider in its place. What are some examples of carbon compounds with the highest ratio of carbon by weight (or volume)?
So you frequently hear that supermassive black holes have masses millions or billions of times greater than that of that of the Sun. This got me to wondering: how much of the universe's mass is tied up inside of black holes?
By all means, we have figures like the percentage and rate of urbanization, the definition of primate cities, and figures for population density; however, I've yet to find any datasets or indices which indicates the actual numerical urbanised area (i.e. km^2 ) per country and/or its location, nor of the proportion of city populations to their total national population for comparisons. Do any exist?
I just went to make an offer on an item I'm interested in, and it popped up with suggested offers of 5%, 10%, and 15% off of asking! It also gave me an option to enter my own offer below that, but I thought this was an interesting new development. I already knew what I was planning on offering before clicking over, so it didn't influence how I'd offer, but I wonder if we'll start seeing a lot more offers that are closer to asking price.
Granted, I got an offer for 40% below asking on something this morning, so I don't think it's going to stop people from sending lower offers. Just thought I'd share what buyers are seeing on the app for those of you who only sell.
Up front, my house isn't pristine. I've made it obvious to my agent, and I'm assuming some conversation has happened internal to their firm and the buyer/agent who made the offer. I do not have any reason to believe my agent has breached their fiduciary duty. It's quite the opposite actually. I'm just looking for external opinions on the situation.
Basically I'm just not feeling great with the buyer getting 2.4%, the MLS advertised percentage to the buyers agent, cash back on the sale since they just happen to have their real estate license. Their current offer is still below asking and it's an agent from the same firm as mine so those are definitely pushing me to think about things more. I absolutely wouldn't mess with any commission on the selling side. Negotiations are going to happen. Again just looking to see if it is reasonable to use that line item in negotiations.
Just to round off, a tennis ball has a mass of ~5.8g, whereas Earth has a mass of ~5.8X10^e24 kg.

Questions 1: Are there practical differences between using salt ratios which include the weight of the water and the weight of the vegetables vs. a salt ratio that includes the weight of the water only? The amount of salt used when considering the weight of the vegetables with the weight of the water to make the brine clearly adds more salt to the fermentation. For example:
2.5% ratio of salt to vegetables+water:
0.025*(100 g vegetables + 100 g water) = 0.025*200 = 5 g salt. This gives a w/v brine percentage of:
5/100 = 0.05 = 5% brine strength
2.5% ratio of salt to water only:
0.025*100 g water = 2.5 g salt. This gives a w/v brine percentage of:
2.5/100 = 0.025 = 2.5% brine strength
The former is thus twice as strong of a brine percentage as the latter. To what extent is this in conflict with general brine strength recommendations for say carrots, which are often fermented between a 2-3% brine strength? Will it only affect how salty the end product tastes or are there other considerations like the duration of the fermentation time?
Question 2: For the same weight of vegetables, how does using different volumes of brine affect the fermentation when the volume of brine differs? Depending on how much brine you use, this affects the absolute amount of salt in your fermentation. For the following example, I'm using brine strengths that only consider the weight of the water alone.
100 g vegetables fermented in 100 g of a 2% w/v brine strength means that there's 0.02*100 g water = 2 g salt in the entire ferment.
100 g vegetables fermented in 200 g of a 2% w/v brine strength means that there's 0.02*200 g water = 4 g salt in the entire ferment.
In the second scenario, the absolute amount of salt is twice that of the first (4 ÷ 2 = 2) even though the brine percentages are the same. Will this affect the fermentation in any way? Or, will this only affect how salty the vegetables taste afterwards because there's more salt to season the vegetables?
Question 3: Is there a lower limit to how much salt needs to be added for a given weight of vegetables? For example, let's say you're making brine by accounting for the weight of the water only. Next you then pack in your vegetables super tightly so that you can add only minimal amounts of brine. Will this negatively impact the ferment because the absolute amount of salt you add will be very small compared to if you loosely packed your vegetables and could therefore add more brine at the same bri

I don't know why I find that significant but I do. Thanks 0.14%!
Yesterday I was high as heck and this tonight came into my mind. I suddenly felt like I was the brain just piloting my bone and meat suit, it's crazy as shit so I just went to sleep. I was tripping balls.

ok, where to even begin.. what is even the P??
I also dont know how to find the mass percentage
any help is much appreciated
Nobody uses their time 100% efficiently. The truth is between social media, gaming and television, the vast majority of people would probably be able to carve out enough time to adopt a habit that would transform their lives for the better over the course of some amount of years. Whether it's studying a valuable skill, or going to the gym.
In fact there is most likely someone who has come from far less fortunate circumstances who have been able to do just that.
The issue is that most people (including me) are very lazy. A lot of people don't have the patience to stick to something for many years to see the results.
I was lucky enough that I was able to work part time and study part time to develop a skill that's considered valuable in the job market. If I had to work full time, I would just be too lazy to do the studying part and would rather spend my free time gaming, reddit, netflix and so on.
