According to the scientific method, your theory must be testable. Develop a way to test whether each hypothesis holds true. Be sure to perform your test in a controlled environment: try to isolate the event and your proposed cause (the dependent and independent variable) from anything that might complicate the results. Be precise, and look out for external factors.  Make sure that your experiments are repeatable. In most cases, it is not enough to simply prove a hypothesis once. Your peers should be able to recreate your experiment themselves and get the same results. Have peers or advisers review your testing procedure. Ask someone to look over your work and confirm that your logic is sound. If you are working with partners, make sure that everyone gives their input. Depending on your field of study, it may be hard to run complex experiments without access to certain equipment and resources. Scientific gear can be expensive and tricky to procure. If you are enrolled in a university, speak with any professors and researchers who might be able to help. If you aren't in school, consider reaching out to professors or graduate students at a local university. For instance, contact the physics department if you want to explore a theory of physics. If you find a far-away university that is doing a lot of exciting research in your field, consider emailing them to ask about their research, their results, or their advice for your project. Again, experiments must be reproducible: other people must be able to set up a test in the same way that you did and get the same result. Keep accurate records of everything you do in your test. Be sure to keep all your data. If you're in academia, there are archives which store the raw data gathered in the process of scientific research. If other scientists need to find out about your experiment, they can consult these archives or ask you for your data. Make sure that you can provide all the details. Compare your predictions against each other and against the outcomes of your experiments. Look for patterns. Ask yourself whether the results suggest anything new, and consider whether there's anything that you've forgotten. Whether or not the data confirms the hypothesis, look out for hidden or "exogenous" variables that may have influenced the results. If the results do not support your hypothesis, reject the prediction as incorrect. If you are able to prove the hypothesis, then the theory is one step closer to being confirmed. Always document your results with as much detail as possible. If a test procedure and its results cannot be reproduced, it will be much less useful.  Make sure that the results do not change each time you do the experiment. Repeat the tests until you're sure. Many theories get abandoned after being refuted by experiment. However, if your new theory explains something that previous theories can't, it may be an important scientific advance.

Article: Get to know her if you don't know her already. If you have a mutual friend, ask your friend to introduce you to each other. If you don't, find a way to introduce yourself. For example, if she is reading a book you have never read, ask her about it casually. Or if you have a class together but have never talked, strike up a conversation about the class. Basically, find an entry into conversation and try to engage her.  If you do know her already, learn more about her. This is a great opportunity to think about whether you really like her romantically or not. This may also give you a chance to learn whether she's open to a same-sex relationship. It's important to express how you feel honestly and clearly. Perhaps start the conversation by saying, "I have really enjoyed getting to know you" or "I really love spending time with you." Then tell her that you are interested in her romantically.  This can be a really hard conversation to have. It may also take a while to build up to this kind of conversation. Make sure that your friendship is on solid ground before trying to take it to the next level. Don't rush it! Take your time and decide when the time is right. If she is sidetracked or in a bad mood, choose a different time to bring up your feelings. This can be hard to do, especially if you have a really big crush. However, it is a good idea to be prepared for rejection while at the same time being confident that she may go out with you. This is a balancing act that is important when asking anyone out!  The worst-case scenario is that she insults you, puts you down, or makes fun of you. If this happens, don't let it get to you. She obviously is not the type of person you should be in a relationship with. Just know that if this girl doesn't share your feelings it's not the end of the world. There are plenty of other people, men and women, out there for you. If she says no, stay calm. It may be your first instinct to feel hurt and alone. Try to remember to be proud, not ashamed, of your feelings. Be aware that a girl that doesn't return your feelings may tell others about your same-sex attraction. Just be prepared to be outed before you take the plunge with this girl. If the girl you desire seems open to your advances, whether it is hesitantly or not, make a plan to hang out with her. Don't just tell her you like her and leave the conversation at that. You can ask her to hang out or to go on a proper date. Either way, you don't want to have an opening and not take it!  Going to dinner and the movies is a classic first date. You can get to know each other better during dinner but then you can relax while watching the movie. A first date can actually consist of a variety of different activities. Pick something that you know she likes to do. It doesn't have to be super fancy or expensive. It could just be taking a walk in nature or going to the mall together. Whatever she likes, give it a try!
